The faucets are Kohler faucets and they are probably not brass but are brass colored. Any suggestions you might have will be appreciated.
I wouldn't even think of it! Most fixtures, not matter the brand or what they're made of, are lacquer coated. I know from my experience in the Army that Brasso will remove that coating. If the fixture is solid brass, you'll have to polish it often after that. If the fixture is some other metal you will have ruined it.
if you aren't sure if it actually is brass i'm not sure how well of a job it will do in polishing it. Basically most polishes work by rubbing off the oxide that has formed. I'm not sure how brasso wil react with non-brass metals, the same way iwouldn't polish sterling silver with brasso. if anything might i suggest some sort of home concoction? I Think vinegar was something peoples used as polishing. It has an acidic property to help remove the oxide, but no chemicals to worry about that might mingle with the metal. I don't recall what else they mix with the vinegar. You can just google "home made polish" I'm sure it'llg ive you a list of them Well good luck with your fixtures.
