What goes with pressure washer

Dish SoapVerdict: NONo, unless your model’s manual specifically allows it. Do not put Dawn or another dish soap in the detergent tank or siphon line when the manual calls for pressure-washer detergent. Use an approved product, follow its dilution directions, and flush the detergent system afterward. Dish soap can be too thick for the chemical injector and may damage components in some washers.
