Is Molasses better than Evapo-Rust? Let's find out!

Molasses, Evapo-Rust, Muriatic Acid, White Vinegar, Organic Apple Cider Vinegar, and water (control) compared for rust removal. All of the products were tested over 3 weeks. 5 separate tests were conducted to assess performance, including 2 separate tests on rusty metal, metal flakes (corrosion test), painted metal, and aluminum. Before and after weights of metals helped to determine rust removal and corrosion risks. Muriatic acid is fast but aggressive rusting happens after using it. Evaporust works extremely well and doesn't seem to harm metal. Molasses is slower than Evaporust but seems just as good if used for 3 weeks. Both white vinegar and apple cider vinegar did very well but seem to eat away good metal too. A lot of viewers requested this video--so, thank you and please keep the recommendations coming!

Growing up in a farm community, we used to take a large plastic garbage can, fill it with water and 5 gallons of molasses. Which you got from the 10,000 gallon tank at the feed store, bring your on container, for about $3. We would just throw anything that needed rust removed in the can and fish it out a month later. When the molasses had finished its usefulness, it would get turned into the garden soil. 100% recycled. Cannot say one way or another if this was a good idea or a bad one, but you got to love the ingenuity and the practically.

This video brought back an old forgotten memory about what an old sage friend of mine had told me about many years ago. He was an expert in rebuilding and restorations of cars. Museum quality. To him though, they quit making "real cars" back in the 30's. He had told me about a guy who many years before had sealed up a service station pit and had filled it up with molasses. They would lower a whole car down into it and let it soak for a month or two. It striped the rust off of the entire car. Inside and out. Even places where blasting media couldn't reach such as inside of a box beam. He had mentioned that it only ate the rust and didn't harm any still perfectly good steel. I guess he was right. Thanks again for a great video. Keep up the good work.

[@ohiofarmer5918]

I like the wheels on garden tractors done to perfection as much as possible. I use electrolysis first and it usually softens the paint that all gets removed with a poly abrasive brush from Harbor Freight. By that time, the surfaces are fairly shiny. Immediately after taking them out of solution, we pickle the steel with metal prep that is diluted and then rapidly rinsed and force dried to eliminate flash rust. They will be a light blue and it's fine to do this a few times. Sure beats sandblasting as the surface is pretty much bright steel. We spin the wheel on a garden tractor transmission and apply the primer from a spray gun. Super fast and accurate..Just have the transmission laying on its side and the rubber tire supports it. The differential let's the rotating tire spin. I once painted ,24 wheels in two hours and used glass beer bottles to hold them up inside the axle for drying

I just dumped it today and it had close to a quart of rust that fell off everything including the bucket. It only devours the rust and stops. I'm quite amazed at that one. I used oxolic acid quite a bit. Thank you for bringing that to my attention.

Molasses is my go to for rust removal when I am restoring my old cars. A good suggestion after removing and washing down your posts is a spray and wipe down with phosphoric acid. This prevents flash rusting and phospatizes the metal. The metal will remain rust free and will have a gray etched finish perfect for paint.

[@ProjectFarm]

Thanks for sharing.

[@johnnyjimj]

Since watching your videos I've been using Muriatic acid, it has proven the best to completely remove rust. It's really corrosive and the fumes are extremely harsh and you need to refinish the surface right away, but there's simply nothing like it, and the steel is so well etched the primer and paint really sticks to it. It's fantastic for rehabilitating mechanical components and at $15 a gallon is very effective for the money, but you MUST work outside or in another well ventilated area AND cover the acid lest it rusts steel surfaces nearby! A work-around is to dip the steel in phosphoric acid ("naval jelly") or citric acid afterwards.

Thanks for the great test demonstration. I have the ultimate rust problem, which I am trying to solve with molasses. I have a boat with a raw water cooled engine, which was used in salt water for several years after I replaced the water cooled exhaust manifolds (big $). In 2000 I took the boat out of the water, and I thought I had treated/protected the manifolds. Fast forward to 2018. I finally get to work on the engine, and expected to find the manifolds in nice condition. Wrong, wrong, wrong. About $1500 worth of manifolds completely plugged with rust. Not even a hammer and chisel could penetrate some of the openings! But, I was determined to try to salvage the manifolds (I know, cough up the $1500...but, no, not me). I have tried Evaporust, Vinegar, and electrolysis. All made a slight but pretty minimal dent in the rust. After much research, I finally decided to go for the Molasses. Mixed up farm grade molasses in 20 gallon container, put in a pond pump to try to get into some of the cavities. Left the tub for about 2 months! Finally some progress. I think about 6 months or so in the summer with the pump running might do the trick. Molasses is extremely slow, but very safe for the metal, and extremely cheap. I would encourage you to try a very long term test on extremely rusted parts with internal passages...this is the ultimate test for salvaging either expensive or irreplaceable parts (read antiques). I have tried to research what museum restoration shops do/use, when say, trying to de rust something like the Monitor (Civil War submarine), but have not had much luck. At any rate, thanks for your great tests and demonstrations.

Impressive!

[@patrickmclaughlin61]

I met a couple of guys who restored vehicles. They would take engine heads etc and put them in a 44 gallon drum full. Diluted to about a 40 or 50:1 ratio. Came out like they were pretty near new.

[@dirtybird4976]

Definitely surprised by the molasses, I never heard of that little trick, but now I know for the next rusty job. Evaporust honestly really is good, I've used it multiple times but seeing the comparison and little experiments showed it. Most stuff your going to be removing rust from is probably something that you aren't worried about losing paint or coating anyway so

[@ProjectFarm]

Thank you for the feedback

Loved this video, keep up the good work! Still here to bug you for solder vs crimps!

[@ProjectFarm]

Thank you very much! I need to do this one soon.

[@terryschabert7929]

@@ProjectFarm According to the Air Force, a properly crimped terminal will have less resistance than solder, and will stand up to at least as much pull as a solder joint. In fact, a pull test is required on each batch of wire/crimper-adjustment/terminal to the point of failure, with the wire breaking b4 a pull out of the crimp.

[@bobkinney2430]

Rule of thumb.....it depends on the quality of connection you need. Crimping is quicker, and can be used in most situations. Some connections are more sensitive (certain audio, video, and controller connections) and should be soldered. This is from over 40 years experience in electronic repair.

[@robplotts9412]

Much respect to the military but a correctly soldered connection will make a more efficient connection. However crimping allows the mechanical connection to the sheathing which will allow for a better pull out resistance. Soldered connection is best by far along with some silicone and shrink tubing . When I'm goin to do a soldered connection I will secure the wires together by zip toeing the sheathing to sturdy locations.

[@terryschabert7929]

Are your connections critical to operation? Is the resistance a factor? Is the signal a tiny current? Is vibration a concern? Is the connection subject to Hot/Cold/ moisture/cycling? In those situations, a PROPERLY made crimp is the way to go. Think about it. Solder, of any current blends, is still a higher resistance and is softer than the wire. Solder deteriorates over time, under the conditions given above. A crimp, properly made (tooling, adjustment, with a ratcheting, non-reversing ability, will crush the wires such that the total circular area is completely enclosed with no gaps. It becomes the equivalent of a solid wire, and any surface corrosion that exists on the wire becomes a small percentage of the total resistance presented to the connector. I agree that sometimes a solder connection is the only way to go. Some cheap PCB's have holes to solder wires to; some military connectors use solder to pins or sockets. But try to find a soldered connection in a high power (multi KVA's) connector. I guess a proper TEST might be a good idea here. I state all of this to show that a good test is not just solder something up and make it fail. This subject is fraught with controversy among engineers, so Project Farm may be a little out of his league on this one. No offense. It depends on what you want to test FOR.

[@cap2c484]

[@lesliehowells]

I read this on a car restoration forum, and thought you all might find it interesting: "What is happening with this is the mixture of Molasses and water ferments creating ethanol. As is known, ethanol creates havoc with anything of a ferrous nature if not highly diluted, i.e.; gas tanks, fuel lines, etc. So, it is logical that it will remove rust from parts over time. Doubtful if any paint would be removed from the mixture, but it should do a bang up job with surface rust on just about anything given sufficient time. Molasses also generally have a very high sulfur content which can also become acidic in nature under certain circumstances."

Thanks for sharing.

[@NobleNobbler]

Am I correct in that these were in solution for 3 weeks rather than the whole test taking 3 weeks to perform? I use a fairly concentrated acid in a coffee container and come back after 30 minutes. I think when you approach 3 weeks you have more than approached "buy a new damn bolt" territory of trouble.

[@LukeTheJoker]

Think of it less for bolts and more for vintage machinery that can't easy be replaced.

[@louf7178]

The bolt is just example material.

[@xenonram]

This reminds me of the office episode when Kevin can do math really well when the units are pies rather than dollars. 432 pies/72=6 pies.. $432/72=??? The bolts are a stand in for any type of steel you want to remove rust from.

[@jmm242]

After using vinegar for 12 to 24 hrs you have to wipe off the scale. Pure clean metal is underneath. It is very easy to wipe off or rinse off with water. Vinegar will dissolve galvanization too. It will dissolve aluminum as well if left for 48 hrs. You also need more vinegar, the more volume the more it will work.

Great point. Thank you

[@ThomasSlaney]

One thing to keep in mind is the stoichiometry: your acid is being consumed for the muriatic acid, vinegar, etc. so they will only etch so far until all the acid has reacted, and longer won’t do anything else. Otherwise, I’m sure that aluminum would be gone. As someone who used to dissolve metals in acid for a job, aluminum can be pretty reactive with acid so good that you diluted!

I have used molasses for years. I inspect it in one week, hosing it off with water and a nylon brush or a broom for large pieces. Do the same on the second and if needed on the third. If you forget about it for a month, no big deal but I think cleaning off the grunge every week helps it work. I put barreled actions and the molasses mixture into a 4 inch pvc pipe capped on one end and a threaded cap on the other. It takes off rust and bluing. For larger stuff like a truck door, you can use a small kiddie swimming pool covered with a sheet of plywood. That is where molasses shines. It's cheap. And it hasn't eaten into the metal yet.
