After washing them in warm running water and dawn, spin drying them. Is it okay for me to use the same pad with a different polisher or paint cleaner, eventhough I used a Meguiar's Cleaner/Wax with it. Also does anybody have any tips on which speed to use on Paint Cleaner, or Polish or Sealant or Wax? The numbers on the Dial do they represent 1,000 RPM or what?
