My 1 year old canvas enclosure (Sunbrella) developed a bad case of black mildew spots on the inside. In particular, the piece that fits between the radar arch and the windshield frame. I'm planning to take it off soon and replace it with my winter cover.
But how do I clean the mildew spots off without (1) shrinking the canvas and (2) removing its water repellancy????????????
