If I only stay over knight I don't bother wiping the dust off unless it was real windy. Otherwise I hit them with silicone and a microfiber towel.
Thanks all, its going in for some warranty anyway.
Dave I do wipe them, but I wonder if it happened the other day when I hooked up when it was so cold and that leg was slow coming up (made the auto-retract assume they were up).
I think I need to just leave it alone when its under 10.
