Tips on cleaning a convertible top

I have had great results with a product called Raggtopp http://raggtopp.com/
It's gentle on the vinyl top material and most importantly it wont damage the stitching. I would worry about bleach, at any dilution, damaging the stitching.

FWIW, I have also heard good things about 303

Listen to me.... A very old detailer showed me the absolute best cleaner and detailer for carpet and vinyl. When he showed me the can I was completely surprised. Ambersol shaving cream works wonders on convertible tops, door panels, and our carpets. It cleans and conditions... also smells good. Yes, I'm talking about basic dolla store or Wally world, cheap, Ambersol aerosol shaving cream in a navy blue and white can.

I've owned multiple verts and install convertible tops on a bunch of makes and models. This stuff will take off mildew and moss with ease. It'll also soften and condition older vinyl.

I use a plastic bristle scrub brush. Afterwards, rinse with water or wipe with a damp cloth. Im a mechanic ( my ranger door panel gets DIRTY ). The only thing that gets them clean is Ambersol. It even gets the grease stain completely out....back to original color. Carpets are the same.

Try it....its too cheap not to !!!!!

No to bleach ???? I have used top conditioning solutions with good results. You'd never catch me with any bleach mix anywhere close to my customers or my vinyl tops....and petroleum products are a bad idea for vinyl as well. ( Vaseline is petroleum based ).
