When you sand pitchy wood like pine or laminated wood that has glue in it, the disk will get clogged and start to burn rather than sand the wood. The key to restoring your sanding disk is this product, which you can buy online or at any woodworking store. It’s called a sanding pad cleaner, and it costs about $8.
Start up the machine, push the cleaner against the sandpaper and you’ll see the gunk start to disappear. It won’t completely clean the disk, but it’ll give you just a little more life. It also works on sanding belts.
