Dust in pedal footswitch?

noisepolluter

The switch has been a bit glitchy in my liquid sunshine recently - sometimes I'll get a slight crackle or volume drop after switching. If I cycle the switch again it usually goes away for a while. 

I sprayed a little bit of switch cleaner into the slot through the top of the pedal, which sorted it for a while - I don't fancy taking the pedal apart to get at the switch properly. Any easy way to make sure it's free of dust?

Try  and blow it out with compressed air if you think it's dust. They can just go tits up though, might be easier to swap it for a new one
