Rust removal/conversion with molasses

[jimm]

I was reading the review of Evapo-Rust on the Parts Supply/Reviews sub-forum and found some videos on YouTube about it. While looking at those, I saw other videos about doing the same thing with molasses. Have to admit, that piqued my interest just by the weirdness of it! One of the better ones: http://www.youtube.com/watch?v=8-gBAjEga1s Turns out it is the same chemistry as the Evapo-Rust: chelating with sulfur. You have to use non-de-sulfurized molasses, like that used in cattle feed, not like that found in your kitchen. You also have to be patient - two weeks of soaking, it sounds like. (As one wag on a forum said, "It's as slow as . . .") Another example of using it: http://www.practicalmachinist.com/vb/ge ... ses-90452/

I haven't tried it, but thought I'd pass it along while I'm thinking about it.

Jimm - I just rinsed out My m-38 gas tank that had been soaking with the molasses mixture for about two weeks. I was really impressed with the results. I feel it was truly worth the effort. I got the molasses at the feed mill for about $1.50 per gal. I think the tank holds about 13 gal so I used a little less than 2 gal molasses. Now you will really laugh because I now have it fastened to my concrete mixer with about a gallon of pea gravel and a small amount of molasses mixture. I will try it for a while tomorrow to see how everything works. I will give you an update in a few days. Let me know how your project turns out.
