Have you put storage wax on your skis yet?  If not, don't panic, but follow the instructions in the Toko summer storage manual  The Toko guidelines also work for Swix wax, use yellow/BP/CH10 for cleaning and red/CH8 for storage.  Summer ski care from Madshus suggests purple/CH7 for storage.  If you're lucky, that same red or purple wax will be just what you need for the first ski outing of next season - just scrape, brush and go!
