Selecting 
Buffing Wheels

•  Keep buffing wheels raked out before each 

use and when buildup gets heavy during use  

Raking means to clean buffing wheels with 

a wheel rake to remove built-up compounds 

and metal particles  ALWAYS use light 

pressure when raking wheels!

•  Do not mix two different compounds on same 

wheel  For best results, use a separate wheel 

for each compound  

•  Always use an upward stroke with heavy 

to moderate pressure for cutting  Use a 

downward stroke with light pressure for 

polishing (see Figure 12

•  Wear safety equipment when buffing  If 

polisher forces workpiece out of your hand, 

be prepared for it to come flying at you! 

Wear safety glasses or a face shield and 

a heavy leather apron  Also, wear a dust 

mask to protect your lungs from microscopic 

particulate that will be flying off wheel 

Use caution when polishing plated metals; 

there is a chance that thinly-plated materials 

could be damaged. Light pressure is all that is 

needed for quality work.

Buffing wheels are available for most types of 

metals, some woods, and for different stages 

in the buffing process  Below are pictures and 

descriptions of common wheel types 

Only use buffing wheels with a wheel speed 

rating higher than RPM of buffer.

Loose Domet

Full sheets of domet 

flannel without any 

stitch webbing for final 

polishing  Designed 

specifically for polishing 

guitars, drums, and 

other instruments made 

of wood 

Loose Muslin

Soft feather-edged 

muslin stitched together 

near the center leaves 

the outer edge to 

provide a wide angle, 

fine polishing surface   

Perfect for polishing 

stainless steel, chrome, 

gold or silver 

Airway Hard

Made of 100% cotton 

sheets that are treated 

to stiffen the material  

Pleats in the material 

help hold compound  

These are great for 

rough cutting plastics 

and initial polishing a 

wide variety of metals
