Glide waxes that have graphite, molybdenum, fluoros, or gallium are dirt-repelling and will resist the buildup of dirt on the ski. Also, waxes that are harder to the touch are also much more dirt resistant - providing a glide factor that does not diminish as quickly as you put in the kms. After you wrap up your session skiing on dirty snow, it's important to use a liquid ski base cleaner to clean off your glide zones. You'll be shocked at how much dirt comes off! Definitely, not a great idea to leave all that grime to be mixed into your next wax application.

Grip waxes can be sped up with fluor liquid or fluor powder covers that contain these dirt-repelling compounds. Some Klisters and hard waxes for dirty snow come with dirt-repelling compounds already mixed in. Cleaning off your used grip wax after a session on dirty snow will help a lot for your next ski. Dirty grip wax can get very draggy.
