Hi Jeff, Unfortunately, that's a problem you'll run into with any cutting wheel. We use cutting wax with our wheel and it is like night and day. As long as you reapply the wax you should be able to cut all day without clogging up the wheel. With our wheel, if you gum it up cutting anything soft, just run it through a concrete block. It'll work like a dressing stone and get all of the aluminum or other sticky junk out of the cutting surface. Thank you for the question!
