Different cleaning methods work best for different situations. Choose the right way to clean your belt based on how dirty it is.
Using Rubber Cleaning Blocks
Rubber cleaning blocks remove dust and buildup from sanding belts. They work like an eraser on the belt surface.
Press the rubber block against the moving belt to clear dirt. This method is safe and gentle on the belt.
- Hold the sander firmly
- Gently press the rubber block on the belt
- Move the block along the belt surface
- Repeat until the belt looks clean
Applying Compressed Air

Use a low-pressure air source to avoid damaging the belt. Always wear safety glasses when using compressed air.
- Turn off the sander before cleaning
- Hold the nozzle a few inches from the belt
- Spray air across the belt surface
- Make sure to remove all loose dust
Cleaning With Solvents
Solvents dissolve sticky residue on sanding belts. Use this method for belts clogged with resin or glue.
Choose a solvent that is safe for the belt material. Apply with a cloth and avoid soaking the belt.
