Put talcum powder on to a cigarette paper and close this between pad and tone hole. The talc will stick to the sticky parts of the skin reducing the stickiness'. Wipe a soft pencil on to a cigarette paper and then close this between pad and tone hole'. Place a dry cigarette paper between pad and tone hole, close the key and pull the cigarette paper out'. It ruins the pads very quickly.
Paper is surprisingly rough and acts like sandpaper on the pad skin.
When this has been done only a few times the surface of the skin looks frayed. This pad will not last long and will certainly not seal as well. I hope the above helps with your sticky pad problems. Do remember though, even if using the lighter fluid method, that you should only do this occasionally.
