Clean the Playpads?


I’ve had my Pyramid for a few months now and it’s one of the best pieces of gear I’ve ever purchased. Pad #1 sticks occasionally though, so I’d like to hear some ideas on how best to clean around these pads. Canned air? Work it until it stops sticking? Can they be removed for cleaning and re-inserted? I haven’t spilled anything on it and it stays covered when I’m not playing, so I’m not sure what might have gotten in there. Any help is appreciated!
