Wax on…
When the season ends, the ideal treatment for ski bases is to iron a layer of wax onto the glide surfaces and then leave this thin layer on the bases all summer. Waxable diagonal stride skis should have any kick wax or klister cleaned off, then 2 or 3 layers of either green kick wax or binder wax applied to the kick zone. A paste wax (like F4 from Swix) should be applied to the kick zones (“fishscale” area) of no-wax skis. Ideally, the skis should also kept in a cool location.
The purpose of summer waxing is to prevent the plastic bases of the skis from “oxidizing” and drying out.
Technically what happens is the compounds that make your p-tex base a plastic evaporate from an unprotected base. A good illustration of this is the plastic dash of a car. As the dash oxidizes, the plasticizers become volatile, dissipate into the air (often forming a film on the inside of the windshield), leaving behind a surface that looks dull, even powdery.
