Rust Remover

A while back someone was asking about a water soluble, non-toxic rust remover. Gemplers, "www.gemplers.com", has a heavy duty Rust Remover that is probably what they were looking for. The item numbers are R425, R174, & R997 for qts, gallons, and a 5 gal pail. Hope this helps,

I use the old stand-by, "sandpaper". It is amazing how much tractor time you get when you are using sandpaper. You can sit in the garage for hours just sanding one little part. I think it makes you appreciate your tractor much more when you have done the whole thing by hand, like I have. LOL In all seriousness, my AC713S was done completely by hand with sandpaper. There was no rust remover or sandblaster used. Just a lot of elbow grease. Actually, I usually have very little time for operations like rust removal. Using chemicals or sandblasting takes a dedicated block of time so that everything can can be done at one time - setup and cleanup. If I use sandpaper, I can work a few minutes, then walk away and come back later when I have another few minutes. My 7116H hood has been laying in the garage for nearly a year. Every time I go in the garage and have a few minutes, I will sand a little more paint off it. I am taking it to bare metal because of the rust under the paint. It is nearly finished now, and won't take much more work till it is ready to paint. Did it 5 and 10 minutes at at time. If you only sand one square inch at a time, it will eventually be completely sanded.

Hey Roy, It was me that was asking for info, Thanks for the additional followup. I was looking at the "selective Chellation" type product from Evapo-rust, but ended up with a slightly caustic product from Coretec. Cortec CPL-426 liquid for rust and scale removal dilluted 4:1 with water for dip tank use. Will strip rust from steel and iron, and will pull oxidation from Aluminum, copper, and brass. Cortec CPL-416 dilluted at 1:1 with water as a final rinse agent to be followed by air drying to provide protection against flash rusting for up to 30 days on cast iron, and longer for steel parts. The specific project is cast iron baseboard sections that unexpectedly spent last winter outside under a tarp and got pretty rusty on the mating surfaces and interior. I've had them sandblasted raw to remove 40 years of paint, but needed to get the interior cleaned out. The up side is that I will now have a 25 gallons of solution for soaking tractor parts when the radiators are finished.
