Simple way I used to remove rust from old tools and car parts. Homemade jig from scraps with amazing results in less than an hour.
It's called electrolysis rust removal, you can find plenty of details on it on the web.

This is not an instructional video, it just shows they way I did this. It is for entertainment only!
Don't attempt to do this yourself as electricity and water are a dangerous mix!
My setup is similar to yours except I use a common piece of 1/2" rebar for the anode. I connect my variable 25 volt 20 amp power supply set at 12 volts and the most current I've noticed is a little over 1 amp. It has served me well for many years. Thanks for sharing your method of rust removal.
Very interesting. The best part I liked about this video was your sheet metal bender, simple and awesome, well done....
Electroyltic rust removal is great!
One small thing to, think of, is that on top of releasing hydrogen gas (the risk you wrote about in the video)
It also diffuses hydrogen in the steel, inducing hydrogen embrittlement.
For some parts/tools, that's of no concern, for others stuff, this could be problematic!
For example, it will make a spring brittle, reduce both the shear and tensile strength of fasteners, etc, (especially important on machinery that could vibrate)
A hard tempered blade would also be made more fragile, etc.
One easy solution for these problems is baking said parts in the oven, taking care of not rasing the temperature above the one used to temper the part originally, if you don't want, on the contrary, to soften springs, etc...
There are available charts for time/temperature according to the type of steel, the cross section of the part.
But for short electrolysis, on low load pieces, this isn't so critical!
Hope this helps!
+siouxsettewerks That's very interesting. Do you know of any side effects, embritlement etc. that could also be caused when using the also very effective alternative of phosphoric acid bath dipping? Regards
I seriously doubt that. The method is used to polish vessels in hazardous service. It touches only the surface and removes the high spots.
The gun barrels and other parts ive nade aren't brittle. Lol
Excellent tutorial! I like your idea of making a sheet metal sleeve to fit inside the bucket. I usually use old cookie sheets. Some things I have learned about the process 1: Use approx. 10 feet of re-bar wire between the battery charger and one of the connections to the bucket to put a 1 amp load in the circuit. I coiled the re-bar wire around another bucket to make it easier to handle. Do NOT let the coils touch each other. This will prevent the battery charger from overheating. Expect the wire to get warm to the touch. 2: High amps (more than 2A) = fast cleaning, it "blasts" the rust off. Low amps (2A or less) = slow cleaning which will actually reverse the rust back into iron to some degree and leave more of the original metal on the part. Thank you for making this video!
Thank you and good tips! :)

Nothing but praise to your ingenuity. The reason for the temperature increase is possibly the amount of soda you put; too much. It only needs to be conductive. Be careful if you are using a 220vAC on the line, to feed the power supply (which does not give you a Direct current completely, but a substantially clipped one, btw). Thanks.
I like the round piece you made. I use this method as well so I am going to try that next time. I usually put an angle iron piece in it. I live in a area where a lot of civil war battles were fought and this is the way a lot of folks clean items found from the battles. I had a 40s era wood lathe that had been rusted up. I used this to get everything loose.
If you put a car headlight bulb in series with one of the wires, it'll limit the max current to around 3 amps. It doesn't make it faster but could prevent too much of a load on the charger.
Thanks you, that's a great suggestion!
+Jammit Timmaj If there is an amp gauge on the charger there's another way to control the amperage draw. Start out with just the water in the tank and then slowly add the solution until the amp gauge starts rising. The process may take a little longer but greatly reduces the chance of damaging the charger.
The Small Workshop
+prairie wanderer thats a great idea.
+prairie wanderer So how many amps should I be targeting? Also I have some power supplies that can produce 24v @ 15 amps.
That was amazing! It reminds me of another amazing tip that I tried out with great success. I got the tip from Popular Science. It needs only one chemical. The parts are dipped in its water solution and heated on an ordinary oven. The chemical does not react with iron but removes all rust very effectively.
It has been a long time; cannot remember the exact name of the chemical. I vaguely remember the name as sodium triacetate. I suppose if you search a little you will discover if I gave you the correct name.
I have grown old but I learnt many skills in the DIY way. Thanks to magazines like Popular Science, Popular Mechanics, Mechanix Illustrated, etc. I still become mesmerized by people like you in Self-learning mode and business.
The Grand masters in the old world were born in this DIY way. No university degree can make man such a jewel! The politicians and economists can do nothing to make this world any better but the Dazzling Lights like you can! Pass your spirit down the generations!
+Amitava Manna could it have been trisodium phosphate? en.wikipedia.org/wiki/Trisodium_phosphate
+Dan Maker Hi enthusiastic guy! I suppose you hit the right name. It proves how brilliant you are to correct my mistake only in minutes! Good luck!
You Made my 5 year old knife look good as new,Thank You so much sir
That's amazing but how am i gona get my truck in the bucket?
Use a swimming pool and a welder as power source. Try not to get killed!
Easy, use a shrink ray first then place in bucket. Once done restore to original size.
You mean to tell me that Chevrolet doesn’t already provide one with the purchase of an extended warranty?😉
worked really well, you can also use white vinegar if you are concerned about safety
Nothing new, but simple, effective and very well done.Thank you
Thanks!
I watched, I learned, I subscribed. Then I went to find a bucket, washing soda, some metal, a charger and something rusty.
Same. lol
J' ai pris plaisir à voir comment tu roulais une simple tôle d' acier pour en faire un cylindre, j' adhère vu la simplicité du mode opératoire, et je vais copier ce système, il me manquait juste la façon de maîtriser l' électrolyse, je l' ai maintenant et je t' en remercie.
Add some TSP to the derust solution and it helps remove any oil or grease on the part, and also leaves a light phosphate coating to prevent future rusting.
I use to live not too far from you, Really like your videos !!!
very nice example of electrolysis in a simple to see example. nice video.
Thank you!
The flex sound at :27 prepared me for a digeridoo solo. Great video . Thanks.
interesante la manera de quitar oxido. ¿ que usaste soda caustica, axido salicilico o que otro producto? un abrazo fraternal desde colombia
English: Washing soda is sodium carbonate, Na₂CO₃
Español: Washing soda es carbonato de sodio (o carbonato sódico), Na₂CO₃
I have used vinegar and it worked pretty good. This is cool too!
What I don't like about vinegar is it is not practical to use ten gallons of it to derust large parts. Electrolysis could be scaled easily, using a bath tub for large parts. I've even seen someone use a pool to derust a whole car body.
Absolutely I totally agree
Just subbed you. I think your channel will do well, especially for people like myself who are downsizing. It was a difficult decision for me to give up a well equipped shop with welders, sand blast, metal working tools and a good assortment of hand tools. We felt like we could build or repair anything. After my retirement move to the Republic of the Philippine Islands, I now work out of a closet that holds only the tools I must have to maintain my home. Good tools are VERY expensive here due to import and VAT taxes. Doing more with less is the order of the day here for those of us who still wish to get our hands dirty. Thank you for the video and the motivation.
Thank you for your sub, Jack! When I started this channel I was thinking exactly the same thing: I have too little space and not enough tools. And I figured a lot of people might be in the same situation so whatever solutions I come with in my shop might help some of those people also.
Spooge tank. Great way to remove rust. Exponentially better than vinegar. The washing soda makes the electrolyte a better conductor. Folks use other things as well such as TSP. Personally I'd avoid any acid rust remover. I have a spooge tank made from 1/2 of a plastic 55 gal drum that I lined with sheet metal and bonded together with steel concrete form stakes. I use a 10 amp battery charger with a decent size battery in parallel with the charger. You can watch the amp meter go down when the steel electrode in the tank gets coated with rust or when the electrolyte degrades.
+howardtoob
what are steel concrete form stakes please
I bought them at lowes. Any box store will have them. They are solid steel round stakes about 5/8" diameter and 36" long. They are pre-drilled along the length of them so nails can be put through the stakes and into the wood concrete forms. I hope this helps.
Cheers, Thanks for the Info
This is a museum conservator's method of treating rusted iron articles. It won't bring back material that's rusted away - but it will remove all rust. The charger shouldn't smoke at any point - means you are using too much current - go for a 6 volt charger.
Thanks I appreciate you time and courage to do this video to let us know 👍
nice one. If you look on the instructibles website at the simple and cheap nickel plating processes, you'll see how you can make your tools not rust again. Same plating principle you used here.
I have been using it for quite a few years. I vote for it every time easy simple and effortless... Oh! It won't eat your metal part like most acid baths. btw nowadays I use Carbon leaves much less "crap" in the water. Well done thanks. ;-)
Carbon as in rods from car batteries or carbon fiber or some other source? This seems interesting.
+The Small Workshop Hi no in this case I'm using carbon plates, check ebay for example. not so expensive and keeps everything more clean. ;-)
Thanks for the tip mate!
+The Small Workshop Hi again. Here you have an example from ebay. Look for graphite or carbon ;-) Hope it's a helpfull tip. Merry Christmas www.ebay.com/itm/NEW-High-Purity-99-9-Graphite-Ingot-Block-100mm-50mm-10mm-/151503238880?hash=item23464bf6e0:g:5pgAAOSwj0NUgZ7i
That was a lot more interesting than I thought it would be!
I know this comment has nothing to do with rust removal but how the set-up reminded me of how we ( The Signals Troop) used to very quickly boil up a gallon of water for making tea when attached to the Artillery at Bartton Stacey . Our corporal was an "Electrician Driver" and he knew quite a lot of tricks. 1 opened 1 gall tin can with holes drilled or punched through near to the top rim. A piece of bakerlight rod to pass through the holes. 1 smaller can to sit inside the 1 gall. can that had been perforated at the bottom with small holes i.e. a dart point. Holes at the top rim to take the bakerlight rod through. A length of Heavy duty twin flex with a mains plug on one end (The old 15 Amp 240v. type there) and large croc. clips on the other end. Nearly fill the gallon can with clean water, fit the croc clips, Live to the centre can and other to the outer edge of the 1 gall can. Plug in to the mains supply and switch on. As soon has the water boils, switch off and put loose tea leaves into the centre can. Give it a good stir and leave to settle. Hey Presto nearly one gallon of tea in a few seconds. Highly dangerous and illegal but a quick brew in no time at all.
Use to make my own electrolysis machine for my metal detecting finds, never used soda but lemon juice and salt.. worked very well on coins etc
Marc on copper spread ketchup across it for about 2-5 minutes then just wash the ketchup off with water. if need be use a tooth brush to clean deeper. try this on some pennies and see (:
Yep, done that with more modern coins but older ones need a bit more care, the electrolysis can be turned off as you watch the metal being cleaned, it's a bit harder with the quick ketchup system in which you need to either spread a bit and clean off to see how it's going and repeat but with my way you can see and adjust straight away.... 👍🏼😉
Very good restoration bro 👍👍👍👍👍
great article/blog + video. we'll try it in El Paso, Tx, USA. Thanks again.
thanks for clear concise video without superfluous talk...
Thank you too!
Very interesting. Plenty of work for this process here! My workshop, a double garage, is rust city. I think the garage needs good ventilation
How thick could the max rust be ? Have you tried other rusted objects ? Can the Wash be saved or re-used ? or fresh water each time ?
Doesn't matter how thick the rust is, it will only take longer time, even days in some cases. Water an be reused a lot of times, I've seen someone keeping it for months. I only use the jig on rare occasions so I usually throw the water for convenience.
I love your videos, reminds me of me , much younger, always into stuff!!!
Thank you John!
A useful addition that I use to treat rusted ferrous parts:
Remove rust by electrolysis as shown here & amplified in some of the comments.
Then paint on phosphoric acid & allow maybe half an hour for the protective ferrous phosphate surface to appear, wash in hot water & allow to dry, then spray with aerosol silicone spray provides short term protection in dry conditions.
Longer term protection even in high humidity conditions if lanolin protective "grease" is smeared over the surface .
Most of my infrequently used woodworking tools are refreshed by a a wipe over with phosphoric acid every 6 months or so.
You should make these all fancy and sell them. I would totally buy one from you!
cool way to bend that sheet! however it doesnt seem feasible that u got into the grooves with ur wire brush. and the big hole in the shaft of the chuck? so what gives?
Amazing! Thanks for the tip. I will certainly use this soon. As for the plate bending education LoL on this too.
I have done this before, passing voltage through some alloys of steel will cause serious pitting, and loss of elements in the metal, use only on mild steel,
I have not seen anything about the polarity of the connections. It seams to me that would be important. In one direction, the rust would have a tendency of going from the part to the iron liner while the other direction would seam to go from the liner to the part. I have also seen from other videos where electrolysis in the right direction would make the rust actually recombined with the part, which in my opinion is much better that just forcing the rust off the part. So the question I have is what polarity is used?
Audio and narrative would have been GREAT. What did you use in the fluid and what type of charge did you use?
+James Dayton He noted that it was washing soda (sodium carbonate) which can be found in the laundry isle. This is NOT to be confused with Baking Soda which has too much water and carbon dioxide in it. You can also make washing soda from baking soda by heating your oven to 400 F (or 200 C), sprinkle some baking soda on a
shallow pan, and bake it for about half hour, until it changes composition. You should also stir it up occasionally, just so that it bakes more evenly. It will actually look different, grainy instead of crystalline like salt.
Brilliant job saves a lot of effort
Thanks!
Interesting and brief. Brief is good, but you needed a close-up of before electrolysis and before wire brushing.
Thanks! I still have a lot to learn about making videos.
These are used widely in cleaning cast iron cookware too. We have one made from a Rubbermaid garbage can.
I have a drill that has the bit stick in it. The bit isn't rusted into it but the part that spins to make the hole where the bit hoes larger and smaller is locked. Will it hurt my droll if I hung this part in there.
Cool way to clean off the rust.
Thank you, glad you liked it!
The Small Workshop great video - thanks. You can also use Muriatic Acid - works well
+Verum Quaerere Seek Truth I keep Muriatic Acid on hand all the time. For rust removal do you use it straight or diluted? If so, what ratio, for how long? Any info would help a lot of people. Thanks
John Michael Hi there, the dilution I use 8:1
(8 parts water to 1 Muriatic Acid) - also known as hydrochloric acid. Obviously use gloves, protective eye wear and most importantly a moulded respirator (mask) --- hurts you a lot when inhaling ---
I soak, then wire brush, soak again, then wipe off, then use Brake & Clutch Cleaner and blow item dry
Good morning to you and thank you very much for the info. Have a great day. I have rust removal in my future. : )
I may have missed it but what type charger are you using? Is it just a conventional charger for rechargeable batteries?
In the video there was an old car charger. Now I'm using a 12 volt 3 amp laptop charger. Basically any 12 volt transformer with a few amps should work.
I like the white vinegar method of rust removal Because i didn't need to go out and buy a charger i just needed a bucket and white vinegar which i already had on hand
Obviously, the rust on the outside of the items was removed quite well. I am curious as to the internal surfaces? Was the rust completely removed from the hidden internal surfaces as well? Perhaps the addition of a cheap aquarium type pump would increase efficiency and shorten the time involved in achieving the desired result, thereby reducing the potential damage to the charger. Just a humble suggestion. Great video, by the way. Very concise and easy to understand. Thanks!
Well, the chuck in the video worked flawlessly ever since, so some derusting was made on the inside too. Also I've noticed the inside of the threaded holes to be clean. I now use a 12 volt 3 amp laptop charger which does great for the size of this jig, does not heat at all and cleans parts in around one hour.
+The Small Workshop Thanks for answering my question so quickly. Keep up the good work.
Amazing!! most certainly will try this,,,, thank you, nice video
I use vinegar, household and salt few spoons depends, and immerse it in a bucket then with steelbrush you whipe it away. I usually let it immerse a day or so.And I put vaseline on it.
one part Molasse two part water works on Motorcycle fuel tanks too , leave for two weeks and shake it around every couple of days , works well
I hope you guys can help me, I set up a similar solution with an aluminum bucket a piece of wooden holding a caliper and it kinda worked, I used a regulated power supply that you can set the max amperage. While the rust did go off the caliper, it just starting rusting again or attracting the rust that was already dissolved in the water.
The caliper looked very rusty at the end, worst than before but the rust was easily removed by a wire brush. It did work better with a rotor however, looked almost new but didn't remove all the rust, it gets to the point the rust "keeps" adhering back to the part.
Do I need to keep changing the water? It did get very hot and made a lot of hydrogen, to the point I set up a fan nearby to dissipate.
apple cider vinegar works well to remove rust from metal as well. Always good to see video's like this though. I like to see different idea's like yours
Thanks! There are many ways to remove rust.
I might have missed it but, what solution did you use?
sodium carbonate Na₂CO₃
If you put a resistor or an old small lead/acid battery in cuircut, smoking of charger should stop. I have used an old, but working 230v 100 watt bulb, in cuircuit to damp down reaction time.
Great tidbit - thank you! In fun... if 12 vDC works in an hour, would 50K vDC work in one second? Grins....
witam jaka jest to soda i jakim napięciem jest elektroliza pozdrawiam z Polski
You wouldn't have to wire brush it at all if you left it in longer. Another point is to dry it quickly after removing it from the bath to avoid light surface rust from forming again. A hair dryer set on high will do that quickly which is key and will dry any nooks and crannies which is also important to prevent rust from forming where you can't see it.
+mrfester42 there is always this black oxide residue left over that needs to be brushed away. You also have to oil the metal if you do not want it to rust again. As the process leaves the metal very clean, and oil free.
um make sure the heat on your hairdryer is OFF, because by drying with heat you you provide energy for any endothermic reaction.
What did you use for a power supply ?
Can we use it iron scuba cylinders (Inside I meant) ? Thickness of them 4,1 mm
I ll test and after proces I ll turn the scuba cylinder on a tumbler with grinder granuls :)
nice job all the best john.
bradturbo44 Thank you John!
Still have to work like hell by brushing the rust off. What about salt, vinegar and aluminum foil?
looks easyy way to do
can you show us some of yellow passivation. wht we will need for it and the way pleaaaaase steve
what did you put in the water???? is that plain tap water???
quick note is that anything that comes out of this process is likely to rust very quickly as it wont have any oils on the surface, be sure to treat it with some sort of bonding agent, could even lightly blue the parts or some such
Thank you Marco, I knew about it so I used WD 40 on the parts as soon as I've finished them. I forgot to mention it in the video, thanks!
+The Small Workshop , good thinking however wd40 and CRC type products tend to evaporate pretty quick leaving minimal residue, I like to use machining oil or if that's unavailable then engine oil works to as they both have much lower viscosity and are much more stable in general, cooking oil can work aswell
Do you connect the positive lead to the device, or to the iron sheet?
Will this work faster if you use more voltage?
some mad sheet metal skills
LOL!
You might want to try Evap-o-rust. I have two videos on this product you might find useful. Great video by the way.
They don't sell it here.
The Small Workshop You could order it from Busy bee tools and have it shipped.
Not sure what country you are in but shipping costs might be expensive.
if you want the sheet steel to come clean without brushing. Just hang a piece of rebar from the wood and REVERSE the Neg and Pos leads. All the rust will go to it. This is how plating is done.
Thanks for speeding it up!
can the scrap iron be aluminum? is washing soda the same as baking soda?
NO and no! ua-cam.com/video/LsPrK4AjQ7k/v-deo.html
Just drop it in standard vinegar you buy from the food store for a few days. Acts like a total rust convertor transforming it into ferric phosphate (hard black coating). Have done it myself and works superbly. Simple and cheap. Plus you can re-use the vinegar.
So a few days is similar to one hour? It's like saying a hand saw is the same as a circular saw only cheaper.
Not in terms of time but for many hobbyists it's a simpler option if they're not pressed for time.
Awesome press
Thanks for the video! Where do you get sodium carbonate AKA washing soda?
+Joseph Stokes The laundry soap section of any larger grocery store. Next to products like Tide and 20 Mule Team Borax powder, etc.
Or via some Amazon/ eBay retailers these days... :-)
What about the black pitting? Can it be removed? The electrolysis alone doesn't do that.
Pitting stays, it's not always black, sometimes it's shiny metal, but the pit itself stays, since that metal is gone.
The Small Workshop
I was sepecifically referring to the blackish color. Sorry if I wasn't clear. The way I see it the discoloration can only be removed mechanically.
Thanks for the video. Hope to use the idea soon.
Thank you too!
Best stuff I've ever come across is Boeshield T-9 ...
Huh ?
Yes. Looks like new with massive rust pits.
Hi, what voltage or current are you using, cheers.
Now I use a 12 volt 3 amp laptop charger. In the video I used a 12 volt 1 amp old car charger, but it was a little underpowered for the size of this jig.
After the de-rusting do you treat the items with anything? I'm thinking wd40 or something? Sorry about the dog.
I oil them with different kind of oils depending on their use. Usually fine machine oil/compressor oil.
Chris Williams vegetable oil or camomile oil works best, the latter for tools etc.
LOL and then you have me... Who just rinses it it water and sray paints it LOL aaaaallll done
After cleaning reverse polarity and use scrap in center to clean the walls.
The parts looked like new? what kinda shops do you have over there?!
great video thanks for sharing,looking forward to more educating videos from you...
NICE VIDEO VERY INSTRUCTIVE, DID YOU USE SALT OR WAS SOMETHING ELSE?
+Juan Guerrero Thank you! It was washing soda (Sodium carbonate).
love it. but that steel bending thing... why you show off! ;( can I use foil? I cn bend that like no one can
Can I use TSP in the water instead of washing soda?
THERE IS A DELETE BUTTON YOU IDIOT. TRY PRESSING THOSE THREE STACKED TINY GREY BLOCKS AT THE EDGE OF YOUR COMMENT . YOU'LL PROBABLY WANT TO THANK ME OR PAY ME BACK SOME DAY, BUT JUST PAY IT FORWARD TO YOURSELF.
What the heck is "washing soda"? It's kinda odd that you didn't give us a good look at the parts before treatment. Makes you wonder...
Yeah I wondered the same thing
It's sodium carbonate. This is all high-school chemistry really.
this is just electrolysis... washing soda is sodium carbonate, and sometimes used in laundry - hence the name.
It's washing soda. For example, "Arm & Hammer Super Washing Soda Detergent Booster". It's not hard to find.
So my problem with this method iis that it unevenly pits and deteriorates the metal. I triedd cleaning some old roman couns with electrolysis and it just obliterated them. I think the bucket of sand may be more effective. Nice video though
Really liked your video. wishing you lots of success.

washing soda .. what can i use instead or what chemical is this? i'm not from US or UK or any primarly english speaking country
It's sodium carbonate (not bicarbonate). Can be found all over the world, it's used as a detergent. I also live in a small country and found it in two options, cheap basic detergent for the poor people and as fancy eco detergent, very expensive but it was basically the same substance. Else google electrolysis and see what alternatives you have.
+The Small Workshop thx i'll look it up
Great job! But are you okay with all that pitting on the bracket?
Thanks! Pitting is where the rust was eating the part, so I don't really have a choice.
+The Small Workshop
I knew that the pitting was caused by the rust, in my line of work, that part would be unacceptable. I was really just wondering if you had some sort of simple repair for that as well. I always enjoy learning something new, or just seeing creative solutions to any sort of problem.
Will it stay rustless
Μπράβο! Ωραίο κόλπο!
very good these video congratulations
Thank you!
what kind of soda? is this like baking soda? NaHCO3?
Washing soda or Sodium carbonate (Na₂CO₃). Depending on where you live it should be available in various brands in the detergent section of supermarkets. In US Arm&Hammer is a popular brand.
I can't find "washing soda" in Europe. Only baking soda. Does it have some different name here or it is only available in the US?
I'm in Europe too. It's used as an eco detergent, you might find it in supermarkets or online.
Washing soda is sodium carbonate, Na2CO3 (2 sodium, 1 carbon, and 3 oxygen molecules). Baking soda is sodium bicarbonate, NaHCO3 (1 sodium, 1 hydrogen, 1 carbon, and 3 oxygen molecules). I found this at naturesnurtureblog.com/how-to-make-washing-soda/.
And that site says you can convert baking soda to washing soda by baking it at 400F/200C.
