Supertune Eco Friendly Base Cleaner is Dakine's citrus based degreaser. After warm spring rides or some unfortunate encounters with dirt/rocks/mud and the occasional tree well, this cleaner is the best way to remove the dirt and grime that cake the bottom of your snowboard. Use it with a rag to clean your base, then do a regular hot wax treatment. It's also great on that layer of dust that accumulated in your garage over the summer.
