X-Pert Pool, I have always cleaned my automatic pool cover each spring using dish soap and water, scrubbing it with my pool brush, and siphoning it off with my pool cover pump. As much money as my cover costs, I would like very much to try the 303 product you mentioned. I went to the website and it basically told me I would spray the product on the vinyl. However, I don't imagine that would be the way to go, due to the size of the surface area. Can you tell me how to best go about applying the product to my automatic cover?
