evaporust

I just used some Evaporust product to remove rust on some small hardware that would be difficult to sandblast. I let them soak in this solution for a few days, then rinsed in water and put on SPI black epoxy. It all seemed to work fine. Have any of you guys tried this stuff? Results? Opinions?
 
phosphoric acid is the main ingredient in most every snake oil . ospho , milkstone remover and many others do the same job. i use milkstone remover and have for years as it is much cheaper than most others . i buy from dairies around here since they buy it by the drum. all are alike in the residue will cause problems if not washed well while wet .
not sure on evaporust as i have never used it. they claim no acids in it . could be like molasses which works pretty good.
 
It's suppose to be totally safe, and after a couple of days, it did a great job on the small bolts and hardware that were pretty rusty. I rinsed thoroughly and blasted them in SPI black epoxy.
 
I used evaporust on some tubing that I used to build a trans mount. I rinsed off the stuff and wiped it with acetone, then SPI expoxied it. No issues and its been over a year. I noticed it doesn't seem to leave any residue behind unlike the acids.
 
I believe its true that evaporust doesn't have any acid, but it also has a short life. It can be used on any type of metal including alum, without harm, and doesn't desolve metal like acids do so its easy to rinse off since it just lays on the surface of the metal. Its much safer than acid in everyway, but its expensive and slower. It cleans metal as well as removing rust, I use it for cleaning alum castings, although it doesn't do a great job of it.
 
I have not used it on car parts but my dad (83!) collects old hand tools and small farm stuff. Anyway I bought him some and WOW is all I can say. For his stuff, it's simply amazing. He bought an old rusty, gummed up Stanley hand plane from the turn of the century. Left it in there two days and it came out nearly like brand new. We didn't know it had brass and engravings on the steel. It came out rust free, no residue and even the brass was bright. A few painted pieces weren't touched at all, enamel was perfect. I have not tried refinishing over it, so I have no input there, but I can say it works for rust removal.
 
Never used it but will look into it for the heck of it and try it on some useless pieces I have around first.
 
I used the brand that the Home Depot sells. Did a good job of getting the rust out from the inside of an old motorcycle gas tank.
 
molasses from the feed store works well and is fairly cheap.
Agreed but Evaporust requires little to no clean up. It's thin as water and the parts are rinsed with water and there don't appear to have any residue at that point. I'm usually dealing with larger parts so I don't see it working for me, but after using the one I got my dad, I'm going to try it on some small parts.
 
molasses cleans with water and can be thinned with water . personally i like milkstone remover. it's cheaper and works as good as anything .
