I have seen many a discussion on this as it is a problem with that trim when it gets old. I have the luxury of selling cleaning sprays at work so I have tried alot of things on it. In the end I found a simple method was a can of silicone spray. I go round with a can and absolutely soak them in the stuff then go over with a cloth and just lightly buff it in.

Not permanent but looks like new for a good month or so before I do it again.

I once paid a triple figure some for a professional valeter to come out and after cleaning he told me theo nly thing they couldnt clean up was the trim and that they had never come across such a difficult trim to clean up!
