There are no chloroflurocarbons used and the can and its components are fully recyclable.
With Frostbite 248 there is no reason to bother with carbon dioxide systems. There are no bulky tanks or expensive parts to replace.
Spray Frostbite 248 directly onto a cotton wool ball and place on a tooth with a pair of tweezers. DO NOT spray directly on a tooth surface. Frostbire 248 is available in a 248mL aerosol can.
