Try gently rubbing the white areas with a white pencil erasure. Or use a Mr. Clean Magic Erasure. Also Chemical Guys make a spray called Trim Clean that works well but is pricey. I use blue painter's masking tape to cover the edges of the black trim when claying/polishing/waxing. It's less work and faster than having to clean it afterwards.

The local Honda dealer probably has a detail shop there where they wash/clean cars. I would ask the detailers instead of using a product that might damage the trim with long term use. I have used Armor All product in the past, but I didn't take my own advice.
