Pressure Washer Storage: Essential Tips for Longevity

Proper pressure washer storage is crucial for extending the life of your equipment and ensuring it’s ready for action when you need it. There are five essential steps to correctly store your pressure washer, whether it’s for a short period between uses or for long-term winterization. Neglecting these steps can lead to costly repairs, such as damaged pumps, cracked hoses, or engine issues.

Clean Your Pressure Washer Thoroughly

Before storing your pressure washer, a thorough cleaning is paramount. Remove any dirt, grime, or chemical residue from the exterior of the machine, including the engine, pump, and frame. Use a damp cloth and mild soap, then rinse with clean water, being careful not to spray directly into electrical components or air intakes. This prevents corrosion and keeps the unit looking good. For gas models, ensure the air filter is clean and free of debris.

Drain All Water and Fuel

Water left in the pump, hoses, or spray gun can freeze and expand, causing irreparable damage to internal components. Run a pump protector or antifreeze solution through the pump for gas models, or simply drain all water from electric models by disconnecting hoses and running the unit for a few seconds until no more water comes out. For gas pressure washers, it’s also critical to drain the fuel tank or add a fuel stabilizer. Stale fuel can gum up the carburetor and prevent the engine from starting.

• Disconnect all hoses and attachments.
• Run the pump briefly to expel residual water.
• For gas models, drain fuel or add stabilizer.
• Apply pump protector solution.
• Clean the exterior thoroughly.

Even if you’ve drained the water, a small amount can remain in the pump, especially in colder climates. Using a pump saver or non-toxic RV antifreeze is a simple yet effective way to protect the pump from freezing and corrosion. Connect the pump saver bottle to the water inlet and follow the product instructions, typically running the engine for a short period until the solution exits the pump outlet. This lubricates internal seals and prevents mineral buildup.

Store Hoses and Accessories Properly

Coil your high-pressure hose neatly, avoiding kinks or sharp bends, which can weaken the hose over time. Store it in a cool, dry place, ideally hanging it to prevent crimping. Do the same for your garden hose. Clean all nozzles and the spray gun, ensuring they are free of blockages. Store these smaller accessories in a dedicated container or a storage compartment on the pressure washer itself to prevent loss or damage. Keeping everything organized makes setup much faster next time.

Choose an Ideal Storage Location

The best storage location is a dry, temperature-controlled environment, such as a garage, shed, or basement. Avoid storing your pressure washer outdoors or in areas exposed to extreme temperature fluctuations, which can degrade components. For gas models, ensure the area is well-ventilated if there’s any residual fuel vapor. Elevating the unit slightly off the ground can also help prevent moisture absorption from concrete floors.
