Once the pool cover is cleaned and removed, I take it around front and dry it off in the drive way. Here I am using my leaf blower to speed up the process. The cover must be completely dry or mildew will result while it is stored over the summer.
For safety's sake, I use hearing and eye protection when I use power tools.
A co-worker of mine once removed his pool cover on a hot and sunny day and left it on his lawn for only twenty minutes. The result was that he had a large scorched spot that lasted for several weeks.
