How to winterize an electric and gas pressure washer

10 STEPS

Winter conditions can wreak havoc on the internal components of electric and gas pressure washers if they are not stored properly. Want to winterize your electric or gas pressure washer? Don’t worry –you’ve got this.

WHAT YOU'LL NEED

Step

Empty detergent

Step

Place the detergent hose into the container to drain leftover detergents

Step

Reconnect the hose and fill the detergent tank with water

Step

Flush until the tank is empty

Step

Use fuel stabilizer

For gas pressure washers, you’ll want to protect the fuel system. You can use a fuel stabilizer solution to prevent fuel from becoming stale when stored. 

Step

Run the machine for 2 minutes

This will circulate the stabilizer throughout the fuel system.

Step

Turn the pressure washer off

Make sure the pressure washer is turned off and disconnected from the water source. Confirm water is not left in the unit by engaging the trigger on the gun. 

Step

Connect the pump saver hose to the pump inlet and press the pump saver button

Pressing the pump saver knob releases the antifreeze content. Keep pressing until the fluid exits the pump outlet.
