Pressure Washers FAQs

Is dish soap safe for pressure washers?

• While you can use diluted dish soap in a pressure washer, it most likely won’t provide the level of clean you could get if you used a detergent specifically meant for pressure washers. 

Do pressure washers connect to the tap?

• Yes. Commercial pressure washers require plenty of water to operate, and the water source needs to be pressurized enough to flow into the unit. We recommend that you connect to an outdoor tap rather than an inside tap. 

Can electric pressure washers overheat?

• If you leave a pressure washer running when it is not in use, it can overheat and ruin the unit’s pump. Do not let a pressure washer idle for more than five minutes. Constant water flow is what keeps the pressure washer working and cool.
