Swix Base Cleaner Liquid 500 ml is designed to clean ski bases and remove wax and klister. Begin by scraping off as much wax as possible. Moisten a piece of Fiberlene with the ski cleaner and rub the base until wax and dirt are dissolved. Wipe clean with a dry Fiberlene. The active ingredient, a low-aromatic hydrocarbon, effectively removes grease and dirt. The aerosol is long-lasting, less flammable, environmentally friendly, and practically odorless compared to most other ski cleaners.
