I've just renovated the two varitone front seats on my '62 Moggie. When the seats were saggy and crumpled the dirt and stains on them could have been described as 'an interesting Patina'. However, now they are padded and firm again they just look dirty and stained....

Has anybody out there had any success with cleaning the years of ingrained dirt off a vynil car seat? and if so, what product or method did you use to do it.
Any help would be appreciated.
Thanks
Woo.
