after you have finished buffing, take a screwdrive holding it against the pad, then turn on your buffer. Works great. But dont try this on a foam pad you'll tear them apart. Just make sure that you hold the screwdriver in a way. That the pad spins away from you. You dont want it spinning towards you, when holding the SD on the pad. Works great. Use a light touch.
For wool pads I spur (or screwdriver) it good on the buffer. When finished with the pad I then stick the pad in a bucket of hot soapy water rubbing it with my hand as to clean. Remove give a few shakes throw it on the buffer and spin it a few seconds on high speed. For foam pads skip the spur stage (unless you have the special rubber spurring tool) you will ruin the foam. when they load up I go Go straight into the bucket as before.
Here is a spur for the wool pads: http://www.google.com/aclk?sa=l&ai=...~~&mode=pg_pla_us_exact&rct=j&q=wool+pad+spur
