OK, my brother burned a copper-bottomed stainless-lined kitchen pan real bad
recently. He says they have exhausted all mechanical means of restoration and
are now looking for chemical means to remove the burned-on residue. Personally,
I really doubt he has exhausted ALL mechanical means - I doubt he's tried
milling it off, or even sandblasting, but that's sort of beside the point.
Anyone got any clever ideas?
I remember my chemistry lecturer saying they used chromic acid to clean
carbon deposits of test tubes as it was one of the few things that would
dissolve carbon. I really doubt that you would want to do that as he
said it's nasty stuff, he said only the chemistry technician or himself
was allowed to use it because of the hazard. What it would do to
stainless I don't know but I would have thought a good scrub with some
silicon carbide or aluminium oxide loaded into a sponge would clean it up.
Is the copper on the outside - I suspect so. Which means SS inside.
Sounds like trying CLR first. Should not mess with stainless but might
help dissolve some of the mess.
Sulfuric acid - think battery acid - buy a motorcycle battery and a bottle...
return the battery for the lead. BETTER yet - the heavy duty drain acid.
It is Sulfuric acid. It might take out some of the hydrocarbons.
If it is burnt on brownish layer - LYE is your buddy.
A better description on burned-on would help - I bet oil.
I once took a chunk of SS I had turned and it was the scrap part -
put oil on it and put it into our oven and put the oven in self clean.
Beautiful brown finish.
Red hot metal and oil...
Drain cleaner - Drain-o contains metals and lye. Use it outdoors.
And if it eats the pot - so be it. Doesn't eat a drain until you use
it to much.
