I know a trick t making the white go away and the trim look brand new!
First you can use a tire shine or something like armor all for vinyl, and you pour some on a towel. Then you rub it in on whatever surface you'd like. After that take a clean dry towel and rub over the same surface again.
Not only does the white dissapear but the trim pieces look hydrated and brand new. I do it all the time on my cars for a fast fix!

However after the tire shine or Vinyl conditioner fades off, the wax residue will still be there.
