You may have used an abrasive cleaning stick to clean the gunk out of the abrasive belt on your belt sander, but what do you use to clean the abrasive drum on your drum sander? A giant sheet of abrasive cleaner, of course.
As far I as I can find, there are two options: a 15″ x 20″ sheet of 3/4″ crepe rubber backed with piece of 1/4″ plywood from Highland Woodworking, or a 13″ x 20″ x 1-1/8″ thick cleaning pad from Busy Bee Tools. Run either pad through your drum sander just like you’re sanding a piece of wood. The pad will unclog the abrasive, making it cut better, and prolong its life.
Highland Tool’s abrasive cleaning pad will run you $99 while Busy Bee Tool’s pad will only set you back $38. I’m not sure why one is more than twice as expensive as the other.
