- just a video on my personal experience trying to remove rust with molasses
it doesnt matter the ratio of molasses to water, you just have to wait until in ferments (starts to smell like old malt liquor)
starting ratio is 9 parts water 1 part molasses...
feed or food grade it does not matter...
it takes over a month to remove rust but this is modern day alchemy (i read that somewhere)
I dumped five of those grocery store jars into a 55 gallon drum, filled 3/4 of the way full. After about 3 weeks the sugars fermented and it started to gather foam on the top. That batch lasted months and cleaned numerous parts. Once it sets up, its just a waiting game. Still much cheaper and less dangerous than most rust treatments. Works perfect for old motorcycle tanks.
You think the fermentation has something to do with it?
rust 911 is safe and only if you buy 1 gallon is it close to being affordable !
2 problems 1 in temperatures below 50° molasses and water takes a lot longer to work. 2 Use a pressure washer to wash off rusty residue dry quickly and add primer any moisture causes rust. I never did any scraping or a brushing or anything else. It’s great for getting into cracks it is awesome, especially thin metal and even jewelry, scrap metal it made it look new. Painted items the paint slides off like it was stuck to the metal I now have a Dustless Blasting set up. Down side it stick and cover smell draws rats and other animal
PPG sells a product called metal prep. It is a liquid that is sprayed on fresh metal to prevent that rust flashing after cleaning. Can be bought at automotive paint stores. After metal prep, prime and paint.
Had an old corrosion seized H-D 1942 WLA engine and soaked it in 10:1 molasses for a month and it freed up the motor to be easily disassembled.
Ok I bought gallon of rust 911 cost roughly 20 for a 5 gallon treatment it will work in 48 hrs to 72 ! But huge investment . I like the results you have with your test ,if you not in a hurry it is more cost effective and just a phosphorus additive keep wet for 20 minutes and your good to go ! Wash and dry use por 15 if applicable ! Good Video
Don’t forget to use Phosphoric acid straight after you remove it from the molasses and dry it... this ceases the oxidation process.... pretty much primes the item and it be painted straight over it without an etch primer%%% I prefer to use the primer as it fills in pitting etc and leaves the painted surface in a smoother state. ....It does take time however maintains the integrity of the item being restored and it’s the best process I have ever used... and cheap
I've mixed food grade 20•1, just had to soak a few days. Also I reused the batch a few times, just skimmed the foam off the top. Also if you have a dollar store, sometimes they've got molasses. Thanks for the tip about feed molasses, duh on me.
Thanks for taking the time and trouble to help sort out some things for many of us!
Hoping you can indulge me with some questions I have: So in looking at molasses available in Amazon, I notice that there is molasses and then blackstrap molasses (there are also other designations I'll bring up later). In researching blackstrap molasses, I learned that it is inferior in terms of taste and is what they give to the animals in parts of the country where the distinction amongst molasses types are appreciated (e.g., Kentucky, Tennessee etc). So my take on this is that molasses that is bitter, acrid and has less sugar is rebranded as blackstrap for markets whose consumers don't know any better. In other words, I SUSPECT, but don't yet know, that your feed store molasses and blackstrap molasses are the same thing.
And there are other attributes to throw in the mix: Some types are labeled unsulfonated. Presumably that means that those not unsufonated have sulfur in them. But maybe this is a process applied only to a type of molasses, e.g., blackstrap, to get it to be a more acceptable taste--I don't know. And then finally there are different sources of molasses other than the usual source of cane: Sorghum, and even Pomegranate come up often.
This isn't a casual review of the types. I am trying to determine which one is optimal for rust removal. Maybe it's the sulfur content that helps in the process. If so, one would want to avoid the unsufonated. Do you have any insight on this? Any comments about my hypothesis regarded blackstrap?
Excellent video. IT seems like warmer weather might speed things up.
Great video Chris! Yes molasses is a long process. I use another method. Lysol toilet bowl cleaner. Wait 2 days, wire brush your parts. Rinse with water and TSP. Dry your parts right away, to prevent flash rusting. Buy a case of 4 at Costco for $20. Make sure your doing this outside or in a well vented area. As well as gloves an eye protection. I've done this on quite a few parts for my 66 Chevelle Malibu. I don't have a video but I do have pictures of a head light bezel if your interested in seeing them.
Great stuff! Really helpful. Thanks bud!
Maybe you should have heated those bottles up a bit. Made them a bit warm, that way it should have flown a bit better. But I'm not sure, never tried it myself.
Although this thing works great, if you're not short on time.
I think the only difference between Food grade and feed grade/farm grade is the sanitation and quality control
It’s probably the same stuff
Thanks Cris, I appreciate all the hard work, now that I know how it works I will try it.
It works better in warm weather
What if you kept spraying your undercarriage with this for like a week or two? Or what if you applied it in like a 2 to 1 ration with a brush and then maybe wrapped what you could in saran wrap?
Good post, good to know. Ive trie vineagar, and ive tried lemon juice, I forget which one, but it took the rust of and the old beer can label. It was my oldest and was my favorite. stuff happens ha ha
wtf molasses how do you know this stuff!
If you use electrolysis you can achieve the same results in 24-48 hrs with good car battery charger and alkaline water solution and some sacrificial metal. Coat cola bath will remove the surface residue that appears after rust removal soak.
ive known about that process for years, but im not comfortable leaving a battery charger hooked up for that long.. i will try it in the future, though
Hey Chris
No problem. Been using this method for years never had a problem apart from earring out a charger.
Enjoying your videos. Keep them coming.
I see this is an old video, but want to ask about vinegar vs. molasses. Is there any reason why molasses is preferred? Seems the vinegar wouldn't have that fermented smell that turns some people off. Not to mention the attraction of bears.
Vinegar attacks good metal, Melasse not.
This was very entertaining. Thanks for the vid!
Just had a thought; what if you combined the molasses process with electrolysis? Has anyone tried this? Did you degrease parts before dipping?
You have to get all grease off before..
Ok, after all that work... You left that stuff outside? What?????????????????
I threw all that stuff away.. it was left over parts
Ospho, the kemah cowboys use it on the fleet.
looks like it worked good , if you have the time
it works really good but not really worth it to set up
There is cooking molasses and fine molasses. Which one?
they both work the same
2 days in Evaporust
What is your mix for wax and grease remover?
to clean greasy parts or before auto paint? I’m not sure what you are talking about? what are you cleaning?
Before painting
I go to my auto paint store and get a gallon of their in house brand... not sure the name.. from AJ Foyt paint in Houston, tx
Thanks.
