Good info to be sure. The only thing I would add is that everyone who owns ANY type of pressure washer, be it gas or electric, should always have a can or 2 of this on hand. And use it liberally after every use. I doubt there is anything you can do or use that will help a pressure washer pump to last longer. It's available everywhere, not just Ace.
