You have to soak it? ain: Just spend the $80 and get some POR 15! :mwink: At least you can paint with it!

 

POR is the best since sliced bread :thumbup:

 

Never heard of it!!

This is a first to hear of this stuff..tho it does sound like something that would work..would take a really big vat to do a body in tho..

I purchased Rustbeeter about 2 years ago. It does work as promised, removing corrosion from places no blaster can reach, and without removing ANY metal, not even on a molecular level. It is a superior product for removing rust and corrosion, especially from small or intricate parts. I had a severely rusted gear on a threaded shaft, rusted into one piece. After 3 weeks of immersion the rust was gone, and the gear was free to turn on the threads again.

If you need a part cleaned quickly, this is not the product for the job. If you want near perfect corrosion removal, I know of no other product that does it better. Note this product is a chemical "chelation process", and does not dissolve the rust, but turns it back into steel or iron, and instead of leaving small pits on the good metal surface, it actually causes the oxidized metal to return to iron or steel, resulting in a surface that is closer to the original unrusted surface. (and if the rust was fairly light, it's ready for paint!)

There are major limitations however. As a food by-product it has a serious problem with mold, and within weeks there is an ever-present layer of mold on top of the rustbeeter. Persons having mold allergies shouldn't use it. And after 2 years of use, the product is starting to reek from the fermentation process and at this point can only be used outside, a problem during winter as it will freeze. It also attracts any bug that's attracted to sweet foods.

Another problem (or advantage) is the ability to remove almost any type of paint. I stuck a lightly rusted license plate into the rustbeeter, and 2 weeks later not only was all the rust gone, but so was all the paint. We now use it to strip paint off small and intricate objects like antique house door locks, old metal toys, antique tools, and much more. It's great for removing overspray from chrome or plastic pieces!

This paint removal situation does create another problem, as it can no longer be disposed by the suggested method of sewer or septic. With paint solids now in the rustbeeter, it is classified by the EPA as a HAZ-MAT!

One more thing - This product is not for use with some non-ferrous metals, and will destroy aluminum quickly. It will remove corrosion from brass, copper or bronze, but check it daily.

Want more info or assistance with this product, e-mail me. (And note I have no connection with the company, nor do I sell it.)

 

This beet based product is beet molasses. I have used molasses for years to remove rust - it works but very slowly. I think this product should work great.

Rust Beeter

My problem concerns a vintage motorcycle gas tank that is original with the original factory paint on it. I used POR-15 about 12 years ago and last summer found it had peeled and was otherwise useless. After months of searching and questioning friends, I was directed to Elizabeth Radiator in Elizabeth PA (outside of Pittsburgh). After a long conversation, Bill advised me that the POR can only be removed by acid which would also damage the metal. He is sending me some Rust Beeter to mix with water and FILL (to avoid mold growth) the tank for probably 2-3 months while the rust dissolves. My major concern is of course to protect the original paint (1957) and get the rust out. Even after the rust is removed, he will not be able to do anything because the POR will still be in the tank. POR works great-if it works. If it doesn't-as in my case...you're dead in the water. All of these comments are germane to a motorcycle gas tank. BTW, Bill has done over 1500 motorcycle gas tanks and close to the same number of car gas tanks. He is a Studebaker guy through and through. He also does radiators.

I will test it out on a painted piece of metal to see if there is damage potential. Their web site says it will "float" the paint off, only if there is rust under it. We'll see. Thanks for the heads up.

If mold is a problem- and it sounds like it IS- I'd suggest using some sodium salicylate or sodium benzoate. This is used in small percentages in foodstuffs (mostly liquids, like soft drinks) to inhibit mold, etc.

I use it as the fuel for making whistling bottle (and bigger) rockets, so it's readily available OTC.
