It's pointless to apply new wax to a dirty base. Use DAKINE's Supertune Cleaner first.
Before you wax, clean your skis or snowboard with DAKINE's Supertune Base Cleaner. Highly concentrated citrus oils remove old wax, dirt, and other contaminants from your base so you get the most of your new wax. Simply apply the Supertune with a dry cloth and rub over the entire area of the base. Then break out the iron and get waxin'.
