I mash a piece of duct tape into the velcro and it cleans out any hair and lint. Personally I hate dual lock. It's too strong, way overkill unless your tossing your pedalboard around the room. I have to hold my board down and pry the pedals off with force if I want to change them. The glue used to attach it on a pedal is also ridiculous. I much prefer regular, high quality velcro. If it's clean when I get it I don't care.
