Conv top cleaner
 

Is there anything that gets rid of mildew on tops? I have purchased every cleaner about on the market and none of them have gotten rid of it.

Conv Top Cleaners
 

If you truly have mildew on the top, then you will need to use some sort of an oxidizer to remove. Any top cleaner that you can buy, will generally be an acid based or a caustic based cleaner which will have little effect on mildew. A common oxidizer is bleach. But, beware, you do not want to disscolor the top. Dilute some bleach (about 20:1 or less) and then tab a small amount in an area where if the color is removed then it won't be a problem. This should work as the tops hold their color very well in the sun. Let me know how this works.
