NEVER use harsh chemicals on your vinyl!! As one said, a majic eraser with some water, then follow up with 303 to protect it. Nothing makes it look better.

We used Clorox Clean-up for 8 years on our white vinyl and never had problems. We conditioned the vinyl a few times a year also.

Magic Erasers are a must.

krazy kleen. Cut it and rinse well after. all the above have worked for me too.

Swipes, Magic Eraser, SoftScrub w/bleach in order of increasing strength. Use a protectant like 303, particularly after SoftScrub.

Clean it on a regular basis, even if it doesn't look dirty.

roll off and a brush

We've had great results with the Mr. Clean majic eraers and follow it up with Swipes. If it's already pretty clean.....JUST SWIPE IT!!!!!!!!!!!!! They clean and condition the vinyl. :)

We used to use simple green, but now Magic Erasers.

What Steve Said...
 

"Roll-Off", great product. Not always easy to find. I do know that West Marine has it though...

simple green has alkalides in it. not a good idea. Put some on your hands and don't rinse it off. It will burn/crack your skin. Mix up some diluted simple green and put it on your lawn. Noting will grow there for about 3 years.

do hot use Chloride chemicals ( cleach, Chlorox, etc)

as told by a chemist friend. chloride cleaners break down vinyl ( poly vinyl CHLORIDE)

it opens up teh pvc molecules. it gets clean at first, but thes broekn down molecule chains colelct dirt and it is a never ending cycle
ever notice how often you need to reclean the bvinyl when using chlorox? that is why. I used it on my first boat until I learned this.

I have the best luck with 3m vinyl cleaner myself
