Just used the Leverage last weekend. Stuff worked great, even took off the black stains on the top of the headrests where the cover had rubbed it from trailering. I found it actually worked great for the cleaning the dash as well.

I use awesome from the dollar store and trust me i have tired everything from soft scurb to simple green nothing works better and it only cost $1.00

thats what was alkin about the magic perasers

Magic Eraser

DITTO! Works great. I rinse off with clean water and then treat with vinyl uphostery cleaner.

same here, :D

I used roll off today it works great

Another vote for Magic Eraser.

I used Fantastic this weekend for the tough stains and finished with a good vinyl protectant. Great results!

swipes if that isn't enough call Dan Dillon from swipes he has ssome stuff I am sure. His contact info is on the bottle. Also as a last resort and I dont recommend it but it works and works well is Easy Off oven cleaner the lemon stuff or scrubbing bubbles spray it on let set for a minute then use soft brush in circular motion follow with swipes and then a good vinyl leather conditioner do it twice. If you dont condition it it will dry out and crack.
