Just like anything else you buy, a phone, computer, vehicle, etc., it’s important to take care of it. Buying a pressure washer is no different. During the warmer seasons, maintenance is pretty easy, but during the off-season (winter), winterizing your pressure washer is the most important thing to remember. 


Thinking you can just store your pressure washer in a shed, a warehouse, or your garage without the proper care could cost you a lot of money. The good news is, you can easily prevent this from happening. Don’t spend money on repairs or a new machine, when you can follow this easy 8 step process to winterize your pressure washer.

5 Tools To Winterize your Power Washer

Winterize a Hotsy Gas Pressure Washer - Antifreeze


Before winterizing your pressure washer check that you have antifreeze and fuel stabilizer! Always check the user manual for winterizing your pressure washer or if you have any questions consult with the manufacturer or contact NorTex Sales & Services and ask an expert.

Winterizing a Hotsy Pressure Washer With No Float Tank:


1. Prepare a gallon jug (with hose connection) of antifreeze. Connect the garden hose inlet fitting to the pressure washer inlet. 

2. Connect a trigger gun to your pressure washer.

3. Turn the gallon jug valve on so the antifreeze can flow into the machine.

4. Turn the machine on, wait roughly 30 seconds, then press and hold the trigger gun until you see the antifreeze. Then press and release the trigger gun a few times to make sure the antifreeze gets into the bypass system.


Tip: You can aim the trigger gun into the gallon jug or a new clean bucket and reuse the antifreeze. If you decide to reuse the antifreeze, consider using a filter (an old t-shirt) to make sure no debris or small particles end up in the bucket. 


5. Run antifreeze through the system for a good minute or until you see the antifreeze spray out of the trigger gun.

6. Turn off the gallon jug valve.

7. Turn off the machine. Press the trigger gun to relieve the pressure.

8. Disconnect the garden hose from the machine and prepare it for storage.


If your machine has gas remaining in the tank use a fuel stabilizer to prevent that gas from gumming up causing a blockage in the lines. Make sure to remove all detergent and water from the pressure washer machine as well.
