The cleaning process does not remove any weight material. Weights must be kept clean while being grabbed and stored. Do not change the surface properties of the weights (e.g. scratch weights) during cleaning. If the weight is dusty, clean the weight or area with clean anhydrous ethanol. Weights with regulating Chambers should not be immersed in solution to prevent the liquid from entering the chamber.
