Wipe the surface of the cue stick with a clean towel, removing all surface dirt, dust, chalk and oil. Do not disassemble your stick for the restoration process.
Burnish the stick with an undyed leather cloth. Rub evenly all the way up and all the way down the full stick so that you contact each section of the stick with the exact amount of pressure. This cloth will create friction on the surface, which can help to repair minor nicks. The friction also closes some of the pores in the wood surface, making the stick more dirt-resistant.
Inspect the cue stick for or cuts that have not disappeared after burnishing. Apply two to three drops of water to these areas and burnish again. The water combined with the friction from the burnishing can help to draw out the wood, evening out damaged areas.
Sand the cue stick only if absolutely necessary to remove damaged areas. Wrap a piece of fine-grit sandpaper, preferably 800- or 1,500-grit, around a sanding block. Lightly sand all the way up and down the shaft so the sanding is even. Do not concentrate on one area, even if there is only one nick or scratch; sanding in one area results in changing the shape of the stick.
Sand the tip of the pool stick with fine-grit sandpaper to achieve the smooth-edged, mushroom shape. Burnish it with the leather to restore smoothness.
Apply a thin layer of cue wax to the shaft. A variety of products are available for this purpose; follow all specific product instructions regarding application methods. The wax will restore the cue's shine and will help to protect it from future damage.
