No need to remove it. Just hose it down, then clean with warm soapy water, then hose down thoroughly, dont leave any residue. Then take the pads out and get a blow torch, and flame them for a while. Not to long, but you will see when yoou do it, they burn like little red bits, and when it is done there arent any left, if you understand me. You can do a search on the subject too
