At least once a year (@ end/beginning of season), I try to clean the blades thoroughly. I usually use a damp dishcloth and push/pull it around the blades. Ir's ok, but not as clean as I would like.
Any suggestions?
Try going up on it with a vaccum cleaner.
If possible, I remove the guard from around the blades. Often this just means removing a few screws. Once that it off, you can use a wet rag with a good detergent to clean the blades. Just make sure you have unplugged the fan! Most of the time, the blades have some greasy residue on them that requires more than a dusting.
