Okay, so I know that every set of instructions for opening your pool in the spring includes cleaning and drying your cover before carefully folding and storing. I've done it many times. But when it comes to cleaning, I'm starting to think I'm wasting my time. I make the cover clean and pretty, store it away in a plastic bin where nothing can get to it, then in the fall put it back on and within a couple of days it's dirty again. All that's really on it is a ring of general dirt and some dried-up petals from flowering trees. As long as I get it nice and dry, why not just put it away dirty? I refuse to believe that dried-up dirt can harm it while folded up in the dark. Am I off base?
