I have a white car and I think part of the black film that accumulates is from the rubber. While cleaning my car the other day, I was over wiping on my sunroof trim, and the filth was getting on my white car, and it was difficult to get off. While trying to get it off, i would pick up some more from the trim and the cycle would continue...
Yikes, you need to sort this out. That'd drive me nuts. Shouldn't be that tough, some of my bought-very-used vehicles were just like that and they're fine now.
I had read that using dawn to wash your car to remove old wax is ok, but it can dry out the rubber and vinyl. So if dawn would dry it out, wouldn't Rubbing Alcohol? I think if i got those trim pieces clean, my car wouldn't get as filthy. I just don't want to dry them out.
The "Dawn vs. rubber" thing is vastly overstated, usually by internet experts who are full of hot air. Not remotely likely to be a genuine issue. Similarly, the IPA will take off the "dead"/oxidized rubber but I've sure never had it do real damage.
There are a bunch of appoaches that work for me...just keyed in a few (e.g., Klasse AIO topped with either KSG or Collinite 845) and decided to then *delete* those suggestions because I've decided to keep this simple.
For starters, youu really/obviously need one thing on your shelf- Griot's Rubber Prep. Freakin' miracle product when it comes to cleaning rubber and plastic trim. Get a bottle and if it doesn't work out OK I'll be utterly astounded.
Use that to clean the rubber (you could use some IPA first to get the worst of it and save the Griot's for after that). Then protect it with something that doesn't run in the rain, "go bad", or attract dirt. I like Ultima's Tire and Trim Guard Plus (think that's the name), a sealant made for such surfaces. Lasts for ages.
Then maintain it with regular (i.e., after every wash) treatments with something like ValuGard's Fast Finish. Yeah, it's a "QD that leaves protection behind" and/but it works *GREAT* on exterior trim. It's simply perfect for the trim and only takes a minute to use.
Don't use "dressings"/etc., they're just not a good approach. "But don't I need the UV protection that's in [whatever product]?!?". No; my trim is holding up fine without such products and some of my vehicles are a lot older than yours.
I think plastics and vinyls are some of the hardest things to clean on a car, as they can be so sensitive, and very tedious..
Trim can be as easy as pie if you go about it right...my vehicles have *lots* of it and it's no bother at all, been years since I had to do anything major.
Use stuff that stays clean and provides protection. Use stuff that doesn't need to be kept off the paint.
