What to use for rust on edges? Normally, I wipe down my skis and they are fine, but they were on a roof rack and we drove home through rain and they had begun to rust by the time we got home. I couldn't care less about my urban skis, but I just got a new pair of SFBs, and I like to take care of them. Any suggestions for how to remove it? WD-40 or some solvent like that would be too harsh, right?
