Im also a fan of magic erasers, those little soft plastic bristled brushes that come cliped to the can of GOJO work well too. I usually clean with Fantastic then follow up with 303. I wish to hell I had known about 303 years ago before my nice fresh $600 Cig patch faded all to hell in the first season. My vinyl is still in great shape with a lot of years left, I just need something to restore that brilliant white color again.
