Cleaning of a parts surface is one of the most overlooked aspects during the finishing process despite being essential at every stage of the sanding process to ensure a clear, smooth finish. Dust, grit, and other airborne contaminants from prior sanding operations can become trapped in the finish, causing cloudiness.
Bristle type is dependent factors including particulate size and static sensitivity. Larger contaminants, like wood chips from the drilling and machining of parts are best removed with a stiffer brush, while finer saw dust is best removed with a softer brush. Static charge can ultimately clog the brush if not addressed.
