Good video. Thanks for posting it.
Thanks for the feedback, and you're welcome.
This is actually very helpful.
Thanks.
You're very welcome
Great explanation, thank you!
You're most welcome!
Haven’t used Acetone in awhile but it’s very volatile and flammable as I recall and evaporates fast. Careful with it.
Thanks for the information
absolutely what i was looking for. i subbed
Thank you, glad you found me!
@@TheTacticalPainter i had to get some acetone and looked for differences between acetone and iso because amazon kept showing me iso when i looked up acetone and then went to yt to only find a bunch of TTS videos then finally came across your video. keep up the good work
Enjoy the video, thank you for this
You're welcome!
I always have denatured alcohol in my shed. Actually used it today removing sticker glue from a wood cap from my candle. I use it in esbit alcohol stoves for hiking but mostly use it as a cleaner.
Good video, here are two thoughts: (1) you should be able to find 99% isopropyl alcohol, it is a better cleaner for all purposes than 70%, the water in which causes a compromise through slower evaporation (it is only there to aid in its disinfecting properties); (2) pure acetone does not leave a residue. If you have a residue after using acetone, it is either because the acetone had impurities in it (commonly from plastic containers) or because the acetone reacted with brush/cloth you used or the surface on which you see the residue. In any event, if you don't need the solvent / degreasing properties of acetone for a particular cleaning task, it is almost always better to use isopropyl alcohol because it is less likely to react with the thing you are cleaning or the tools you are cleaning with.
As a summary with additional points: Isopropyl comes in various strengths (all the way up to 99%), but it is a residue alcohol. If it burns it puts off a black soot which is very difficult to remove without use of chemicals (such as acetone). Far superior on almost every level is Denatured Alcohol, which is a pure, non-residue alcohol. When it burns it produces no soot, fumes or odors (it is highly recommended for alcohol camping stoves). It does very well with cleaning, so long as the surface is alcohol-tolerant (most surfaces are). Acetone is great if the strength of acetone is needed. The problem as pointed out is that it is a very strong chemical than can melt some surfaces, and it evaporates very quickly. While it can leave a residue (depending on the brand and the cloth used to apply it), it is often used to REMOVE residue from other cleaners, so it is considered a "clean" solvent. Interestingly, some recommend using denatured alcohol to remove any possible residue from acetone. Acetone has strong fumes. Overall, Denatured Alcohol is the best of the three if it does the job... but sometimes the extra power of acetone is required for a specific job. Definitely be sure to test the surface first though, because acetone is what's used to remove artificial fingernails nails; it's that strong.
I use acetone to remove ink and paint from surfaces, to which it does rather easily.
Thank you for this, I was wonder what the difference was between them.
You're very welcome
Thx for video
Can you do a video about difference between thinner mineral spirit and stuff used in paint
Thank you! This is exactly the info I needed. By the way, can I use this on a wood floor before staining?
Yes, it dries super quickly, I would be sure to do it with all windows open and absolutely no sources of spark or flame.
Reminds me of my own channel lol, thanks for info. Here is a subscribe!
Thank you Janky, I'll return the favor
Thanks.
I tried to remove an old coffee stain off the table, 99% isopropyl didn't do anything like it was just water, then I just used some glass cleaner that contained ethanol alcohol in it, it did the job perfectly
Nice! Just needed the right solvent
Great video. I have just treated an english white oak beam with boiled linseed oil and after 3 days its dried way to dark. I obviously didn't sand it enough prior and would like to use acetone to remove the oil before i go back to the sander and start again. Would acetone do the trick and break the linseed oil down so i can wipe it off?
Ooh, that's a tough one. I'm not sure, I would try it on a piece of cut off if you have some before attempting on the actual piece. Problem with linseed oil is it works into the wood and penetrates it, so it's not just on the surface like a lacquer or polyurethane. So I don't know if there is a way to strip it.
Great video. Thanks. Can you speak to mineral spirits, and how it fits into this mix? Thanks. I'm needing a cleaning agent, so I'm thinking denatured alcohol is ideal as I don't want any residue left over on the surface. That said, I hear chatter about mineral spirits too. Is that a good option or have a specific place in your shop? Thanks.
I do use mineral spirits, but only for cleaning out brushes or cleaning up messes. I wouldn't use it as an agent on a product I am selling. DNA is much better for this application because of the lack of residue, fast evaporation, and low Evaporated harmful chemicals requiring ventilation. Hope this helps ☺️

You're welcome
Can you use Acetone to clean up any debris left after diamond etching the garage floor?
Probably, but if your garage floor has a top coat of a plastic or resin I would recommend using acetone it might dissolve a little bit of the top layer. I would use denatured alcohol for this task. Water would be preferred but if not rubbing alcohol might work too, but be sure to do it in plenty of ventilation and with absolutely no open flame or sparks around.
Can I operate the stove at this ratio: Ethanol 68.6%, Methanol 3.7%?
could you use denatured alcohol to clean a surface before you use 2 way tape like around a window frame before you put on 3m window kit for winter??
I would be cautious using Denatured Alcohol on painted surfaces. I would use an Isopropol Alcohol, either 70% or 99%
Hello my friend I do not know what to use I just made an epoxy resin countertop with isopropilyic alcohol or denatured alcohol mica powder effects? thanks for your help
If you're looking to clean it off between sanding jobs, I recommend denatured alcohol, it seems to do a better job bringing dust up out of cracks.
Do you know of the denatured alcohol fuel is the same as denatured alcohol? Can you just the fuel to clean metal before paint? Thanks!
Yes, they're the same, some states banned denatured alcohol as a cleaning product, but they can't ban it as a fuel source, so they put that on the can to bypass that arbitrary law.
I was researching for cleaning bearings and it seems alcohol 91 or denatured are a better bet.
It may be for that application
Hello my friend, can I run a stove on acetone? Is it safe and what is the percentage of alcohol used in the stove?
If you're talking about like a penny stove or backpacking stove I would use the denatured alcohol. Best stove fuel I ever found was Heet Gas Additive in the yellow bottle. It's pure alcohol, no additives, burns reliably, and has no water content. It reliably ignites, even in cold wet weather. Hope this helps!
Can u use denatured alcohol to clean latex paint brushes? I was worried it would damage the bristles...if u can use denatured alcohol how do you go about cleaning them? Soak all the bristles for a time peroid or put a little on and work it through the bristles? Any help would be appreciated.
I'll start by saying I don't have firsthand knowledge with latex paint brushes, but I think what it really comes down to is whether or not the alcohol will act as a solvent to the media you're using with the brushes as to whether they'll clean them off or not. Latex is pretty impervious to most solvents, so I don't think it'll damage them.
And if you're asking if you can use denatured alcohol with latex paint, water and dish soap will dissolve latex paint because it is water-based.
Thank you!
I'm new to your channel thank you for the information what would you suggest for shellac overspray on top of a formica. Air particles settled on the surface
Denatured Alcohol should remove Shellac. Dab it on, let it set, and then rub it off. I don't think it will harm the Formica so long as it's not painted Formica. Try it on an inconspicuous spot first.
@@TheTacticalPainter Thank you.
It worked beautifully with some elbow grease. It's was old Formica and looks brand new now
Glad to hear it worked, thanks for the update, glad I could help!
Thank you for your information! I recently watched this channel about guitar pickups, he removed a ceramic magnet on a pickup by melting the glue using an iron. The ceramic magnet stained the iron. He used denatured alcohol to clean the stain off of the iron. I was wondering if I can remove the stain with an isopropyl alcohol?
Did he use the alcohol to remove it or the alcohol as a lubricant in conjunction with a scrub pad of some kind? I wouldn't use iso on steel due to the water content. The stain was most likely oxidization of some kind or left over adhesive.
@@TheTacticalPainter He used the alcohol to remove it, he used an ordinary cloth to remove the stain so mostly, the denatured alcohol was the cleaning tool. Thank you, kind sir!
@@grecco4037 you're most welcome
Would you suggest to use denatured alcohol to remove wax build up?
I don't know that DNA has the right kind of solvents to clean wax build up. I know that it will strip paste wax off my table saw cast iron top, but as far as taking off the wax protective coating they put on wood to prevent cracking I don't think so. Hope this helps.
You could use Light Naphtha (White Gas), Mineral Spirits (White Spirit), Toluene, Turpentine or even Limonene.
Where can I find out where can I find it?
Where can you find what exactly?
Is denatured alcohol just isp in higher concentration ? What if you just buy high % isp?
No, Denatured alcohol is ethanol (ethyl alcohol) made unfit for human consumption by adding one or more chemicals (denaturants) to it. Denaturing refers to removing a property from the alcohol (being able to drink it), not to chemically altering or decomposing it, so denatured alcohol contains ordinary ethyl alcohol. Pulled from thoughtco.com
Isn't denatured alcohol unsafe to handle with bare hands because it contains methanol?
Yes, some brands use methanol as the additive to drive out the water. According to data sheets that I see, the concentration of methanol is less that 10% of the solution. When used in our application, it is hardly enough of a measurable dose of the methanol through the skin to have any effects on the body at all. However, if you're concerned, you can always wear gloves or a small baggy on your finger like I do when applying a CA Finish.
I’m in Cali and they banned denatured alcohol and I’m tryna find something similar any advice?
Ouch, so sorry! 99% Isopropyl would probably be your next best bet, and give a little extra time for the 1% of water to evaporate off
@@TheTacticalPainter thank you
You're welcome! 👍
Oh here we go I just complimented the last guy on this subject for making a one and a half minute video now we got a 13 minute video to say what could be said in 2 minutes guess I'll put it on 2x speed... Why the heck people have to talk so much to say something so simple
Cause not everybody processes information the same way. For some they'll take your word at face value and for others, seeing is believing. I've been training people new skills for 16 years, if there's 1 thing I've learned, its that no 2 people learn the same information the same way. Thanks for checking out the video, and it doesn't hurt my feeling putting me in fast forward if that's what works for you. Thanks for the view and feedback, it's always appreciated.
Does denatured alcohol smell bad?
That depends, to some it stinks and to some it's fine. Smells better than paint thinner but worst than rubbing alcohol. If you get natural Denatured Alcohol it has kind of a fruit smell to it. Hope this helps
Denatured alcohol is ok for plastic ? Because i saw a video of body shop that says it leaves a film behind plastic. Better use rubbing alcohol
I use it to clean plastics, wood, resin, marble, and concrete all the time, I've never had it leave a film. It evaporates so rapidly that maybe the film it's leaving behind is actually the left over dirt and grime that their rag didn't pick up.
Maybe.
Do you think that denatured alcohol it's safe also for the car paint (clear coat) if you want to degrease for example before polishing car
I think 99% rubbing alcohol would be the safest option.
99% is more agressive than 70%
It's not so much that it's more aggressive, it's more that it'll just evaporate quicker. Isopropyl having a higher alcohol to water ratio doesn't really make it more volatile against surfaces.
thank u
You're welcome
You can buy 91% or 99% Isopropyl??
yes, 91, 98, 99.9
I added IPA in soap base making process instead of Denatural alcohol and come up with hand burn and fire in all the kitchen.. And then searching about difference btw these both alcohol with burnt hand burnt 🥵
Hmmm… not sure you’d have had a better result with denatured alcohol. I’m going to recommend you seek another hobby if you were able to make alcohol explode all over your kitchen, that’s not how alcohol do, unless you’re concentrating the vapors, in which case, see my previous advice
Where can I find it.
Can you add 70% of denatured alcohol and 30% water to make rubbing alcohol???
No, chemically they are 2 different alcohols. Iso is safe for wound care and denatured is not due to the denaturing chemicals used to expell all water from it.
@@TheTacticalPainter ok.. I have alcohol that's called "general cleaning Alcohol" in a Tin... It doesn't say denatured... I assume because it looked similar to yours in a tin can... it's a 1 gallon
It may still be denatured alcohol, it could also be methanol. If this is the case, then it's still not safe to use like isopropyl. Methanol can have adverse reactions with the nervous system if you have to much skin contact or ingestion. Best to stick with iso or ethanol, which is common in hand sanitizer and is safe for direct skin contact.
Ok...I i dug out the can.... it says isopropyl 99% general alcohol .. I wish I could send a pick
@@TTPSURVIVOR nice, that's good stuff, especially given our current situation post 2020!
Sir where can buy denatured alcohol ?
If you have a hardware store in your area, I would start there
@@TheTacticalPainter sir i am from nepal i sarch many hardware shop bt not find denatured alcohol
@@gopalsomai9446 I'm not sure, it might even be called something different in your country, if it's available at all.
Whats different ethanol sprite and denatured
I just looked up and in many regions it's also called methylated spirits
Can you thin polyurethane with denatured alcohol?
I have never tried that, not sure if it would work, but I know you can with paint thinner. I always follow the rules oil to oil base and water to water base. Not sure about an alcohol to an oil base. I would run a test on scrap first before trying on a final piece.
@@TheTacticalPainter Hi, thanks for getting back to me so quickly. Since you're not sure I'll pass on the denatured alcohol. Can you thin poly with turpentine?
@@Gold-oj8do yes I have seen this done before
@@TheTacticalPainter Thank you, I kind of figured it could be done.
0:43 I laughed
I'm glad I could make you laugh
Did you have to worry about using the alcohol when there are warning about the vapors specifically the one regarding your eyes.
No, I've never had any issues, just keep away from eyes and sensitive capillaries (I.e. avoid picking your nose while working with it). Wear protection where necessary, safety glasses, gloves, etc.
Denatured alcohol for cosmoline? Mineral spirits didn't cut through everything
try 99.9% isopropyl
Everclear is better than denatured as it doesn't have the chemical added to it so people don't drink.
Yes, Everclear is more effective than 70% iso, and less toxic for consumption than Denatured. It still has water content of 5%-10% that we're trying to avoid using with our wood during finishing.
@@TheTacticalPainter I thought the only difference between Everclear and denatured was they added a toxin to the denatured to prevent consumption? Was listening to a podcast on Fine Woodworking with Mike Mascelli and he was talking about that. Could have misunderstood tho. :)
@@e4clark Partially true, it's not a misunderstanding, more if a misconception. Most people think they add the chemicals to prevent consumption. In truth the chemicals added are to expell the last 10% of water from the mixture. Making it 100% alcohol, but in turn makes it toxic for consumption. Everclear is "safe" for consumption, but should be diluted with other substances like Coke or Sprite because it's so close to straight alcohol that just a shot or two can give you alcohol poisoning.
Mag ka ano yan
You can buy 99.9% Isopropyl alcohol that dries like normal alcohol.
I've tried the 99.9% and I still don't get as good of results as the DNA, especially when it's cold in the shop. The little bit of water content makes it take longer to evaporate when it's cold.
Crappy test. You should have used the same surface for all three, like plastic.
You're correct, for demonstrating drying out should be a similar substrate. Plastic does demonstrate evaporative properties, but I was also looking to show saturation into the wood which I talked about at the beginning.
Denatured alcohol is illegal in California
That's what I've heard, it's unfortunate, because it's a great product
You could purchase 99.9% IPA. You just have to locate it.
Aceton never use. Never.
Acetone has its purposes, things that it does well that others don't, like cleaning off ink or paint. Just not prepping wood for a finish.
One person drink this dies 10 h
