Dust Buster (or a generic “canned air” product) is commonly used to clean computer keyboards. Basically, it is cold, compressed air in a can. It works great for blasting unwanted debris from your car’s nooks and crannies. We’ve used it to blast dust from interior vents and to remove dried, crusty wax residue on the exterior (especially around emblems). The air comes out of the can under high pressure and is extremely cold, so short bursts work best. If you’re concerned about the pressure damaging a part, use from a further distance and try light “bursts” first.
