Frequently Asked Questions (FAQs)

1. Can I add a soap tank to my pressure washer?

Most pressure washers today feature onboard detergent tanks. ... Some, however, will not have these tanks and will require the use of a bucket to insert your detergent hose into. After you've filled your detergent tank, make sure the valve is turned to "On" so the detergent will be applied as you spray.

2. Can you leave soap in pressure washer?

You can use dish soap in a pressure washer as long as you properly dilute it with water, but it may not be as effective at cleaning surfaces as other soaps or detergents meant specifically for pressure washers. ... If you are bummed that dish soap isn't going to solve all of your outdoor cleaning woes, don't be.
