Dirty spring snow is a problem that has not surfaced often as a topic. Googling  the topic brings mixed results, so I am trying to tap into the collective knowledge of the club.

Using a fluorocarbon wax with a moly or graphite additive is most likely the best approach to deal with the build up of material on the bottom of skis. Yes? No? How can the sporadic attacks of the grip monster be deal with?

Your thoughts please.....

I can only share my experience from my days as a xc skier. I was using fluorocarbon wax with a moly additive as you suggest. But, I was cleaning/waxing my skis

after each ski, so....kind of tedious but necessary work

I am OK with cleaning and re-waxing. The wax I am using works OK and my skis slip fine, suddenly they feel like they are griping the snow, and I rapidly slow down, then suddenly slip again. Keeping my balance is difficult and occasionally the result is a header or fall. 

So the fluorocarbon wax with additive worked well for you, at reducing the sudden lost of slip?

It worked for my xc skis, but the setup was slightly different:

- xc skate skiing is done on large trails groomed somewhat regularly. Plus season

ends way earlier (typically mid april!) So that makes the snow on which you ski cleaner

(my guess). 

Now, I exactly know what you are talking about. I experienced also the same problem

and have not been able to resolve it yet. I tend to brush nicely my skis to have a smooth

surface and avoid anything that could catch the dirt (???)

OK, from your input I get that using fluorocarbon wax does help, but as temps rise and the snow melts the volume of contaminates on the snow surface increases and will eventually ruin the wax. I guess I just need to get hold of some fluorocarbon wax, try it, and see how effective it is at reducing my problem. I suspect that above tree line there should be a noticeable benefit, and at treeline and lower less benefit, just because of the volume of dirt and pollen in and on the snow.

Some progress is being made.

I indeed think that the situation would deteriorate way more below treeline: more dirt, debris, sap, etc...

I am a SWIX guy. Typically, I would wax say LF blue with some moly wax together. I have some moly

wax I can lend you if you wish to try. I am sure there are some secrets out there! 

A related interesting question would be: as soon as your base gets sticky, and that you have to put

the skins on. Would that affect the performance of the ski glue?

Skins: Sticky - you mean dirty, loss of slip? I guess that if you were to put skins on, some but not all of that stuff would be transferred to the glue. Depending on the condition of the glue, the skins most likely would stick fine afterwards. Spring conditions are hard on skins and depending how often that happened the glue would lose the ability to stick to the ski, more cleaning and fixing.

Thanks for the wax offer, but I will get an alpine flouro-wax. I think I will also need to strip off the wax I have now, clean the bases before applying. Hopefully a couple of secret keepers will show up and help out with few secrets.
