Center caps turned "milky"

What the heck?? I washed the car Sat since it was about 60 around here and when I was doing the wheels I noticed that all four center caps had fogged over. I tried to clean them but it looks like it's not something just on the surface but has faded or something. The car's been in the garage for a month or so and the last time i washed it the caps were fine. There isn't anything in the garage that I can think of that would have caused this issue. And there doesn't seem to be anything else on the car that's affected adversly. Is it just age? Or somethig else perhaps? I think I know the answer to this but I'll ask anyway....any hope of bringing these back to life or am I stuck with getting new center caps?

Thanks for your help
Bob

Oxidation of the clear coat. They get hot. Mine respond very well to polishing.

Thanks I'll try to polish them. What's strange is that I track the car and the brakes obviously get hot,but this is the first time anything like this has happened. Hopefully the polish will restore them

Part of the discoloration is heat, part is chemical reaction with environment. Just be careful on removing it with any abrasive. Polishing compound and a cloth buffing wheel will do a great job.

Mine is looking the same also and have noticed for years. I will get on the rubbing compound right away.

You don't need anything very abrasive. Rubbing compound would be way too much. At least to start with. Just use the same polish that you use on the body. It's just oxidized paint.

Try a finishing compound ......

like 3M 5928. Worked great on my colour crested caps and works wonders on cloudy headlights on my DD Accord too.

Thanks. I'll see if I can find it, but I don't remember seeing anything with that "name" from 3M. I've got a little Menzerna left over...polish and glaze. I'll try them first and see how it goes.
