CLEAN YOUR PADS? - MPC 3000

Has anyone ever cleaned or changed the pads on your mpc 3000? if so how? .... Sometimes pads 9, 10, 11 & 12 will play sounds from other pads ... is there a way I can fix this?

thanks ...

this has been covered before.. look in the bible... look up 60 pads 3k pads

thanks ... I thought i looked good enough but I guess i didn't.
