  • How to removed polishing compound after polish on part?

    Hi Everyone. I recently bought an Eastwood 2 speed buffing machine. I make aluminum parts on a CNC machine. After i get them made on the CNC i do a light buff on the buffing machine. Because my parts have raised sections it causes a build up of white polishing compound that is kind of caked on the high spots. I would assume since the heat caused by the friction it kind of bakes it onto my part and have to scrub it off or use a wet polishing compound to remove the dried stuff. I would think there is a spray or a special trick to removing the baked on compound after polishing. Any tips? Thanks

          You only mention white compound..
          all of the buffing compounds I use leave a black residue and that comes off easy.

            When you say comes off easy your referring too when you use rubbing alcohol after you get done polishing? Yes i have used other compounds but mainly just the white bar for finishing aluminum.

              Yes...after polishing or cutting with any compound and wheel.
              Today I was cleaning a cast spoke sportster wheel..
              The alcohol worked great...99 percent is best!
              Watch for false edges...the light will hide burned compound on edges!
              There is a product that I haven't tried yet called "white out" that is for cleaning off compounds after polishing and or cutting!

              I'll pm you if you want to know about it...its cheap too
