whats the best way to clean the door panels and the front dash ?

I use a windex vinyl cleaner on a terrycloth rag. Works pretty well.

If i ever have bad spots that won't come up, i use this stuff called de-solv-it, a multipurpose cleaning agent.

this may sound wierd but use a medium toothbrush and your favorive vinyl cleaner... works wonders...

I really like this stuff. I've used it on vinyl, carpets, wheels, engine bay, etc... its great stuff. http://www.properautocare.com/hi-c32.html
