The sandpaper on belt sanders, orbital sanders and other powered sanders can get gunked up with sawdust and become less effective unless you clean it. If you have an old tennis shoe around, you can refresh your sandpaper in a jiff. In this video, from YouTuber izzy swan, you'll learn a simple trick for cleaning sandpaper of all types. Normally, to clean sandpaper you would use a sanding belt cleaner or "sandpaper saver". Cleaning the sandpaper on your sanders increases its abrasive life, improves its finish quality and reduces the likelihood of your sandpaper causing any burns or markings on the things you sand. If you don't have a sandpaper saver, however, or don't feel like paying for one, you can just use the bottom of an old tennis shoe. Apply the shoe's rubber sole to the sandpaper while the sand is running and it will clean out all the gunk to make it almost brand new again.
