Not all, but a lot of the "touchless" gas station washes use some rather harsh chemicals to compensate for the lack of any real brushes/rollers, etc. They will certainly strip the wax off of your car (and skis). I would be a little concerned about the lubricant in your bindings. Check your binding for sure. If they need lubricant, you want a heavy grease, not a thin spray on lubricant--those don't last very long.
