Pressure Washer Storage: 7 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 seven essential tips to follow for both short-term and long-term storage, covering everything from cleaning to winterization.

Clean Your Pressure Washer Thoroughly

Before storing your pressure washer, a thorough cleaning is paramount. Remove any dirt, grime, or detergent residue from the unit, hoses, and nozzles. A simple wipe-down with a damp cloth is often sufficient for the exterior. For the internal components, especially if you’ve used detergents, run clean water through the system for a few minutes to flush out any chemicals that could corrode parts over time. This prevents buildup and maintains optimal performance.

Drain All Water from the System

Water left in the pump, hoses, or spray gun can cause significant damage, especially in freezing temperatures. Disconnect all hoses and the spray gun, then run the engine (for gas models) or motor (for electric models) for a few seconds until no more water comes out. For electric models, simply turn it on briefly without the water supply connected. For gas models, pull the recoil starter a few times to ensure all water is expelled from the pump. This step is critical for preventing freezing and rust.

Add Pump Protector or Antifreeze

For long-term storage, particularly in colder climates, using a pump protector or antifreeze is highly recommended. These solutions lubricate internal components and prevent freezing. Follow the manufacturer’s instructions for your specific pressure washer model. Typically, you’ll connect the solution bottle to the water inlet and run the engine/motor until the solution appears at the outlet. This ensures the entire pump is protected.

Coil your high-pressure hose neatly to prevent kinks and damage. Store it in a cool, dry place, away from direct sunlight. The same applies to your garden hose. Clean your nozzles and store them in a designated holder or a small container to prevent loss and damage. Many pressure washers come with onboard storage for nozzles, which is ideal. Keeping them organized also makes setup quicker for your next cleaning task.

Protect the Engine (Gas Models)

For gas pressure washers, proper engine care before storage is vital. Add a fuel stabilizer to the gas tank and run the engine for a few minutes to circulate it through the fuel system. This prevents fuel degradation and gumming. If storing for more than a few months, consider draining the fuel completely or running the engine until it runs out of fuel. Remove the spark plug and add a small amount of engine oil into the cylinder, then pull the recoil starter a few times to distribute it, which helps prevent rust on internal engine parts. Change the engine oil if it’s due for a change before storage.

Choose the Right Storage Location

Store your pressure washer in a clean, dry, and temperature-controlled environment. A garage, shed, or basement is usually suitable. Avoid storing it outdoors where it’s exposed to extreme temperatures, humidity, or direct sunlight, which can degrade plastic components and hoses. If you must store it in an unheated area, ensure you’ve taken all necessary winterization steps to prevent freeze damage.

Regularly Inspect Your Stored Unit

Even when stored, it’s a good practice to periodically inspect your pressure washer. Check for any signs of leaks, damage, or pest infestation. Ensure hoses are still pliable and free of cracks. This proactive approach can help you catch minor issues before they become major problems, ensuring your pressure washer is always ready for its next use.

• Always drain all water to prevent freezing and rust.
• Use a pump protector for long-term or cold-weather storage.
• Coil hoses neatly to avoid kinks and damage.
• Store nozzles in a secure, organized manner.
• Add fuel stabilizer to gas models or drain fuel completely.
