I don't have an indoor place I can store my Hardtop. Last year I had it stored on an old table frame in a relatively shady place... It got horribly mildewed and took hours of overhead scrubbing with all manner of noxious cleansers to remove the mildew from inside the Hardtop before putting it back on for the fall and winter.. Any ideas to keep it mildew free this year? The best I can do is store it in the old stinky shed, but it'll still be pretty much outdoors, just "covered". No temp control, etc.
