I used the Magic Eraser the other day, and all I can say is it looks Brand New!!! 2 answer the question about why it turns gray, I guess it turns white n gray because of all the soap scum residue or maybe you used armor all to make it shine, n this actually makes it look worst after time. But I gotta say tha magic eraser did it's trick. I am thinking of putting some aerospace 303, this liquid is specifically made for rubber or plastic pieces that have to endure UV rays and sun all day long. But I have to order this online, I can't seem to find it in any supermarket or carshop. Whosever idea, was to use the magiceraser on the trim ur F****** Geniu
