Tiger's Crystal shaft cleaner is the best shaft cleaner you will ever use. Just apply the Crystal Shaft Cleaner to a clean piece of cloth or Scotch Brite (3M). Hold the damp cloth or the Scotch Brite (3M) firmly to a turning shaft (lathe), moving gradually from one end to the other. Crystal Shaft Cleaner gets into the pores of the shaft and gets the dirt out. Repeat as many times as needed. Burnish the shaft (fast back and forth motion creating heat) with Qwiz or a piece of leather to close the wood pores.
