I'm looking at a 1984 Dodge 600 rag top and it is really dirty. It has a white top of course. It's been 20+ years since I cleaned a convertible top. What's a good product to remove heavy dirt and mold off a white top. It's otherwise in good shape.

 

My Lebaron has a white top and i used to get asked how do you keep it so clean. I used something like ajax and brush. Did wonders!

 

I'll keep that in mind. The GF insisted we do some work around her house. By the time I got done and could call the owner, he had sold it. I'll keep looking.

 

I have tried everything, different purpose built cleaners, simple green, comet, even bleach, before painting the car.... The most effective I have found is simply using a pressure washer. FWIW I have had the car 21 years and im on my 2nd top. Bottom line, IMO white is not a color to have if you are keeping it outdoors.
