I like most of these, use them a lot, usually great stuff, and two out of three ain't bad.
The Rustolium brand on the far right has Phosphoric Acid in it. It is NOT friendly. It is corrosive to many different steels and I watched some of my iron stuff fizz and bubble in it. It chews paint, chewed up brushes, is bad for brass or anything besides some steel, and wasn't easy on the hands. You bet it's fast acting though, too fast for anything besides the right steel. I'll still use it for some things but I'll be watching it closely. Lucky for me I caught the action quick on the main worm drive housing for the Kansas Save. It's a steel housing but started to fizz and the results could be seen in the finish after I yanked and rinsed it. That stuff would have completely destroyed my main worm housing. I had to watch it closely and remove everything in minutes. Items like the bakelite worm gear are totally forbidden.
The other two are great. I've always found paint to be better, rubber to be better, phenolics come out nice, just a light rinse leaves nice protection and is paintable. You can leave things in it for days and the worst of it is possible darkening or staining of the surface. Easy on the hands, puts Palmolive to shame, doesn't chew up my tools, doesn't chew up anything except rust.
Just a heads up, and I also like sun tea and a 28 oz breakfast coffee.
Edit: Since I mentioned it, The KS Save has been standing here like this completely mechanically done for months. The drive was wiggled into position (not bolted) and has very little play through the 4 worm assemblies. It is made for a regular motor that runs in the 1,000's of rpm and the first three worms zero out in seconds. I have tons of pictures down to nuts and bolts. Sorry I'm bad about keeping my strings up to date or sometimes abandoned. I space and it isn't getting better. The mount needs paint/cosmetics, and some little ditties I've discovered.
