Over time, your buffing wheel will pick up dirt and particles that can scratch your polished metal surfaces. There's an easy way to clean your wheels that will extend it's life and lead to a higher shine.
Buffing wheels are used to remove very small surface irregularities in metal, steel, aluminium, brass, copper and stainless steel. When finished, a buffed surface will be smooth to the touch and have a mirror-like finish.
The best way to clean your buffing wheel is to use a new 36-grit sanding belt and apply it lightly to the buffing wheel when it's turned on. This will remove a very small amount of material from the wheel and leave you with a particle-free surface. The sanding belt is unaffected by this and can be used like new.
Use property safety gear including a mask and eye protection, to protect yourself from fine particles. Check out the video to see how it's done.
