Cleaning Vinyl seats

I use lemon simple green to clean vinyl with, but be careful not to leave it on.....just a little spray, a small brush, and then wipe clean....follow up with a rinse from a semi-wet rag. BUT, t'would be best after that to rub in some vinyl treatment (if you rub in the new "dull" (I forget the term they use) treatments really well, it isn't slippery or shiny.......But it's worth the effort.
