I would like to point out that there is usually a considerable amount of moisture that condenses as the air is being compressed into the tank. For this reason, I'd advise that either you leave the PC unplugged for 10 minutes or so after you've cleaned it to let any residual moisture dry, or purchase an inline water filter. The compressor also makes it quite a bit more convenient for topping up your vehicles tire air pressure (you know you don't do this regularly enough ;) Steve
