FLUOR FREE. PS10 is an economic training and racing wax as well as base prep wax for warm skis. Easy to melt and very convenient to work with. The speed of the iron should be approx. 8-10 sec. on a skating or alpine ski. The wax can be re-heated after cooling to room temperature (10 min) for better durability. It's important to have a good iron to get an efficient melting of the wax. Recommended iron temp: 120Â°C (248Â°F). Replaces the CH10X.
