chrome trim has gone milky?
I have just had the S8 3 weeks now and tidying up trim etc - one thing is bugging me though, the chrome trim has white spots/milky look to it. Tried polishing and some of the marks faded but didn't really make much difference. Looked around the forum and seen that spraying them black is an option, but the car is silver and think it would ruin the look (plus want to keep it as original as possible).
Any ideas of how to bring them back to thier former glory? (obvioulsy buying all new trim sounds like it would be a VERY expensive option)?

Same problem here. I didn't see any write up how to change them. Heard changing those door chrome trims require complete doors disassembly from the inside, which is nightmare.
I wonder if this milky stuff is just a buildup on top of chrome (which should be washable or removable mechanically) or is it permanent damage to chrome, i.e. we actually see white plastic basement under the chrome?

What you have is polished aluminium that has been anodised and covered with a lacquer. The milkyness is moisture getting into or under the lacquer. The only permanent method is to change or paint the trim.

I wonder if i can get them chromed (not sure if its possible with aluminium?), but it sounds like removing them from the car is 'fun'.........hmmm could be a 'live with it' or back to the paint option.....i'm guessing this is a common problem?

it is very common on cars that have spent a lot of time outdoors. Darrenjoe90 has done a thread on his attempts to cure the problem.

The only way to get the trims shiny once more, is to remove the protective lacquer, then polish the raw aluminium to a bright finish.
The problem is once the lacquer's removed, you'll have to keep on top of your polishing. It may however be possible to purchase clear vinyl, and cover the fresh aluminium, protecting it from the elements. (Audi use it on lower areas of the rear wheel arches on certain models vulnerable to stone / grit chipping).
