Dear Grandpa and Cheryl, I have a similar white spot on my '71's roof and I'm not sure what it is or how to get it off, but to clean my vinyl top I often use a soft bristle brush with a cleaner like 409 or Castrol Super Clean (I think that's what it's called). But first I wash the car and the top, and I dilute the cleaner. The brush helps get down in the cracks in the texture.
