Needing to change a still gritty sanding belt because it is clogged and gunked up with sawdust is a different matter.
Why does it always happen when you’ve got just a little bit left to sand and you’re out of new sanding belts? Is it some DIY conspiracy I don’t know about? Possibly.
Did you know you can clean sandpaper and prolong its life? Yep, you can! Cleaning a sanding belt is a cheap and easy thing to do. You might already have just what you need to do it too.
3 Cheap and Easy Ways to Clean Sanding Belts and Prolong Their Life
Sanding Belt Cleaner Pad
Big Rubber Eraser
Corks – Natural and synthetic corks work equally well for this project
The technique is the same no matter which cleaning tool use you use to clean a belt sander although you will probably need more than one wine cork depending upon the condition of your belt and how sawdust free you want it.
Warning: Please take all precautions when cleaning a belt sander as you would when you use the belt sander to sand something. Wearing a dust mask, eye, and hearing protection is a good idea too.
1. While the sander is on a low speed push the sanding cleaner pad, rubber eraser, or cork against the belt. Be careful not to accidentally sand your fingers!
I unplugged my sander for the photos in this post.
2. Continue cleaning until the sanding belt is free of sawdust to your liking. You may need to replace the cleaning tool based on which type you use.
I keep the rare synthetic wine corks around the workshop for sander cleaning and use the natural wine corks for decorative projects.
