I am in a dilemma whether to purchase a pressure washer or not.. All the salt and grime on my vehicle is making me wince as of the moment. Tempted to get one. Besides, it is freezing outside... so anything that will make the washing process quick will be helpful. I could use it for car wash in the driveway rather than in the cramped garage and perhaps for the garage floor. I am not sure if I need one to begin with but sounds like a good idea.. anyone here has one? if so, any suggestions regarding type and brand? Oh and do you use a foam gun with pressure washer or regular water hose?
