Mr. Clean Magic Erasers. I use them all the time. The work great.

2 years ago I cleaned some seats with bleach white (cut 50%with water) and a medium brush. Worked my AZZ off scrubbing everything. A couple days later I was told to try the Magic Erasers......you could see where I left off when I stopped 1/2 way through. Use small amounts of cleaner along with the Erasers, Spray 9 cut significantly or even Windex cleaners will help the Erasers clean even more quickly. I will use nothing else on my vinyl from now on!!!!!

I've had good luck with "Vinyl Shampoo". That's the name! Think I got it through boaters world! Then I top it off with mcguires vinyl conditioner in the blue spray bottle....

lava soap works great

The bad thing about the Magic Eraser is that you can't just try it. Once you try it in a spot, you have to do the rest of the interior. :)

I always follow up with 303.

SOAK it with Simple green for 15-20 min or so. Then scrub with a soft bristle brush thoroughly and wipe off. Spray again, wipe again, it will look showroom and you won't have to worry about a caustic cleaner to boot! It works!

ditto!

What is the 303? I have seen it mentioned a couple of times around here.

vinyl protectant

I swear by Magic Erasers dipped in Quick n Brite, it does the best job. Stay away from anything that has bleach, it will crack your vinyl and so will amorall. We have switched over to 303, it may be more $$$, but it sure beats replacing all your vinyl.
