I used to just throw them in the washer with bleach. I switched to a 200 micron mesh filter sock, rinse them off every couple of days and throw them in the washer once in awhile. They are so much easier to clean!
I power wash mine... easy and fast. I let them air dry and they are good the next day. I tried the filter floss...while effective, it doesn't have the same surface area of filter socks and they clog really quick.
