Suggestions About Model 3 Chrome Trim

Over the course of 3.5 years, the chrome trim on my car has become cloudy with kind of a rainbow tinge to it, like when metal is exposed to high heat.

And as you would expect, a mobile tech once told me that's caused in part by heat (because it's hot in Florida) and part by car washes - any car washes. Apparently the chemicals in the soap from washing the car damage the chrome material applied to the plastic. The mobile tech also told me the damage is permanent, and the only way to fix it is to replace all of the "bright work".

Aside from being kind of disappointed that a car would have chrome attached to it that is not designed for heat or to be washed (now I understand the actual reason they replaced it with black), I guess if I'm going to have to replace it all someday, that buys me some time to experiment with it.

I already tried spray detailer, Rain-X, windex, foaming windshield cleaner, plain wet rag, plain dry rag, and soap. I have not yet tried a clay bar, though I do have one. I also have not tried using abrasives like barkeeper's friend or polishing compound, because I'd have to remove them all from the car first to avoid damaging the paint.

Any other ideas?

I suspect all the damage is from the car washes. The "heat" (aka temp) here in Southern Arizona makes Florida look cold.
