Stainless Rust Removal
No rust on the Prevost, because I don’t have one … yet.
Have some rust spots on the stainless cooktop and with all the stainless on a Prevost I figured someone encountered this problem.
Any experience or suggestions for how to remove rust from stainless steel.

“Try some CLR”
Our coach has a couple of spots where it rubbed up against something and the stainless steel is creased. There appears to be some surface corrosion, oxidation, rust, or whatever it is at those points.
Can I use CLR on that?

Bar Keepers Friend works well on any stainless.

The reason why stainless steel rusts as in Dick’s case is whatever creased the metal transferred some iron to the surface of the stainless steel. Once there is the presence of iron on the surface of stainless it will begin to rust. Manufacturers that work with stainless steel go to considerable efforts to avoid transferring iron from machine tools to the surface of the stainless steel they are working with.
CLR is an acid I think. It might be all that is required. But if that fails stainless can be sanded and polished. It sounds scary, but if you use progressively finer grits, working from 240 to 1500 for example, then finish buffing with red then white rouge it should remove the iron from the surface. Be very careful to avoid the build up of heat on panels. Heat will cause distortion in the skin.

So if the stainless surface would have been “wiped clean” when the incident first happened, then the rusting would never have occured?

Yes, but the effort would likely have been similar to wipe it clean.
We learned in manufacturing to handle, punch and bend stainless steel with the protective “paper” in place. Then if final finishing was required we then removed the protective material. The unprotected stainless which came in contact with steel punching, bending or drawing tools made of steel was going to get a final finish, either a brushed (sanded actually) finish or a sand blasted finish so whatever iron was transferred from the steel tools was being mechanically removed.
If Harry Hoppe is visiting the site he might be able to add to my remarks. He is also a metal shop guy.
