A Little Background
A pressure washer needs a cleaning detergent such as soap, detergent, cleaning chemicals and other cleaning solutions for it to work with the water. Most commonly a pressure washer has a tank for the detergent solution and this makes it very viable for use in various situations. In fact, some pressure washers have two tanks with varying levels of capacity for detergent and most of these pressure washers also have special nozzle spray tips for soap and detergent spraying.
Washing detergents specifically for pressure washers are different compared to regular detergents for cleaning clothes and bathing. These detergents vary but some of them are multipurpose cleaners while some are for car washing.
In the long run, a pressure washer cannot work well with just water – you should just use a cleaning solution or a detergent, soap or chemical for it to effectively clean stubborn stains and the like on any specific material.
