Before you head out on your first ski tour of the season, check your ski base for scratches and dings. If you have waxed your skis over the summer, then the wax must first be removed well and brushed away. Take note: If there are any wax remains, your skins may not stick well.
During the season, dry your touring skis after every tour with a soft cloth. That prevents rust spots and keeps the steel edges sharp longer. If your skis are dirty, you can clean them any time with sudsy water with mild soap. As soon as the base turns white, it is time for another round of wax. And if you notice the skis are gliding as well anymore, you should apply wax.
In the spring or if there is wet snow, a rough textured finish is essential. To do that, the base is smoothed with a stone grind and then textured. Only then can an accumulated film of water be removed.
If you ski down a lot on-piste or in icy conditions, you should have your edges checked out more frequently by a professional edge service. These conditions demand more from them and the edges can more quickly become dull.
Fundamentally, touring skis should always be stored dry at room temperature, not exposed to direct UV rays. During their “summer rest,” you should also generously wax the ski base including the edges. Wax protects the base in the summer from drying out and the edges from rust spots. You can use a more cost-efficient base wax for this.
