Swix Glide Wax Cleaner
After many hot waxings and fluoro applications, the glide sections of your ski bases get clogged with loose wax particles. This cleaner from Swix re-opens the pores of sintered bases (if your bases are extruded, don't bother with this product). It acts on fluorocarbons but leaves hydrocarbon wax in your bases.
To use: saturate your bases (glide sections only) with the product. Brush the liquid into the base with a nylon brush. Let sit for a period of time - even overnight, if you have the time. Then wipe clean with a lint free cloth (such as Fibrelene); this may take awhile as the product is quite oily. When the bases look dry brush with a steel or bronze brush and hot wax as usual.
