My driver and passenger doors on my 2004 Chevy Silverado were frozen after a cold, icy, windy night. I used WD-40 to unfreeze them. After discussing this with my co-workers, I had three different answers... One person stated that I should clean out the WD-40 the best I could and use graphite in my locks. The second person suggested that I use a alcohol-based propellent such as a de-icer and then treat my locks with a silicone. The third did not see any problem with the WD-40. My problem is this- the next time it ices up I am unsure on what I should do. I shouldn't have too many more days of icing up as I will be able to park in a garage in about two months (new house). Until then, what should I do?
I have purchased a can of compressed air, a tube of graphite, and a alcohol-based lock-deicer. I still have plenty of WD-40 around as well!
