How to remove cat piss stain from chome rims

[2003 GMC Denali]

How about Mr. Clean's "Magic Eraser" ?

I mean the Rims are screwed, right? So give this a try. You've got nothing to lose.

If Meg's Wheel Brightner doesn't take it off.. nothing will.

Uh, what kind of cat do is that? A friggen mountain lion? Try washing with Wolfgang Tire and Wheel Cleaner, ( worked on the wife's nasty stained wheels) and finish with Megs Hot Rim Chrome Polish and shoot the cat

This is what happens to cats in Idaho when they piss on our shoes!! (and oh ya, it is a friggen mountain lion)

Okay, he didn't really pee on my shoes; however he was terrorizing some of the local pets...

+1 on the PB spray and rinse, Then I would suggest Poorboy's World Pro Polish on a Flitz polishing ball. This combo can't be beat.

maybe its already cleaned, and needs to be polished.

The wheels appear to be etched and I'm not so sure they are actually chrome. You'd want to be positive about the material and coating first before getting aggressive.

Looking at the back side of the barrel, it seems they might be cleared aluminum based on some of the haziness and what appear to be defects in the protective coat, rather than actual chrome. If the wheels are aluminum and clear coated by some material, they need to be refinished (most likely by a professional). The coating needs to be stripped, the wheel polished to a high degree, then a protective coating is applied. Probably much more effort than is worth pursuing as a project, but with the exception of re-coating the wheels with a durable product, stripping them and polishing the wheel can be a DIY effort.

Now if the wheels are actually bare aluminum (should see black residue when polishing), these can be brought back with some tenacity. I'm thinking you might have to do some fine sanding to remove the pitting and etching, then use various levels of metal polish to remove the sanding marks and haze. But go through the polishes first before touching the sand paper, since completely removing sanding marks from aluminum takes considerably more effort than someone accustomed to working with painted finishes expects.

I have refinished wheels for my own cars and it's a bunch of work. You learn to appreciate why shops charge what they do for perfect results!

Lots of good advice here. If nothing else works I would use a liberal ammount of cat blood, applied vigorously with fresh feline fur. It may not work so well on the stains but fairly confident you would feel better about the whole situation.

No actual animals were harmed in the production of this theory.
