This custom kit provides you with everything needed to clean your optics using the PFC Training Cadre endorsed method. The first step is to use high pressure air to remove any sand/grit that may be present on the glass. Next use a soft, clean brush to remove any remaining dust from the lense. Finish the cleaning process with disposable optics cleaning wipes that are impregnated with streak-free cleaner and a fog-preventing additive. This kit will avoid damage to expensive optics caused by other incorrect cleaning methods.
