Detergent is a very important part of pressure washing, especially with hot water. For every 50 degrees of water temperature, your detergent doubles in strength. Hot water washers generally run about 180 to 200 degrees, (you do the math).

Cold water washers are okay, even with detergent they can’t stand-up to hot water washers. Without hot water you can’t get the chewing gum off especially if it is old. We also use hot water to kill germs and odors in and around trash areas.
