Getting rust off of skis?

Sandpaper. Most of it should ski off after your first session, especially if your hit some iced-up sections. Just don't use a rust remover (phosphoric acid) as it can damage the rest of your ski.

I usually use a gummy stone to knock the rust off of my skis.

Same here!

well a few things, first, like the two guys above, gummy stone is the way to go in terms of getting rust off. second, yea you can drop ptex on the bases anywhere. you can even get some on the edges, no biggie. That being said, you then need to scrape it off which you can do two ways. One with a razor by hand or two with a wintersteiger. I would say just take the ski to your local shop and have them tune it. the 50,000 dollar machine will most likely do a better job than you in your garage. hahaha, not saying you cant hand tune your ski, but someone who gets paid to do it, will do a better job. hope this helps!

gummy stone the edges. fill the gashes with ptex and smooth it down to the level of the base. a shop will be better at this. i would say take it there.

if your lazy bring em in for an edge tune

I use a toothbrush with toothpaste then a burstone on the sides ONLY

this.. nothing beats all the machines a shop has.. damn, im gonna miss working at a shop..

Getting rust of, just ski them
