I used to take mine to car wash and power wash the heck out of them. First thing to do... now that you're going to clean them yourself, is to cut the bands on them so you can open them up and get the spray nozzle in there and get as much gunk out as you can. The reason for the car wash is to leave the debris at the car wash and not my property. I used to go through about ten cleanings with each filet before I'd give up and buy a new one.
