Griots Garage has two products called Rubber Cleaner and Vinyl and Rubber
Dressing. I haven't tried the cleaner but they recommend using it before the
dressing. I have used the dressing on my dash and on the seals between the
doors and the body with good results. To get a catalog go to
www.griotsgarage.com

Be prepared to get a new catalog about once a month though!
