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 key areas to focus on when storing your pressure washer, whether for a short period or for the off-season. Neglecting these steps can lead to costly repairs and premature wear.

Preparing Your Pressure Washer for Storage

Before storing your pressure washer, it’s vital to prepare it correctly. For gas models, drain the fuel tank or add a fuel stabilizer to prevent gumming and corrosion. Run the engine for a few minutes to circulate the stabilizer through the system. For electric models, simply disconnect from the power source. Always flush out any remaining detergent from the soap tank and lines by running clean water through the system for a few minutes. This prevents residue buildup that can clog components.

Protecting the Pump from Freezing and Corrosion

The pump is the heart of your pressure washer and is highly susceptible to damage from freezing temperatures and corrosion. To protect it, use a pump saver solution or RV antifreeze. Connect the solution bottle to the water inlet and run the engine (or motor for electric models) for a few seconds until the solution exits the high-pressure outlet. This displaces any water, preventing ice formation and lubricating internal components. This step is especially critical if you live in a region with cold winters.

• Drain all water from hoses and wands.
• Apply pump saver or RV antifreeze.
• Store in a temperature-controlled environment.
• Inspect for leaks or damage before storage.
• Clean exterior surfaces thoroughly.

The environment where you store your pressure washer significantly impacts its longevity. Ideally, store it in a dry, temperature-controlled area like a garage, shed, or basement. Avoid locations with extreme temperature fluctuations or high humidity, which can lead to rust and material degradation. If storing outdoors is unavoidable, ensure the unit is covered with a waterproof, breathable tarp to protect it from rain, snow, and direct sunlight. Elevating the unit slightly can also prevent moisture from accumulating underneath.

Organizing Hoses, Wands, and Nozzles

Properly organizing your accessories not only keeps your storage area tidy but also prevents damage. Coil hoses neatly, avoiding kinks or sharp bends that can weaken the material over time. Use hose reels or wall mounts to keep them off the ground. Store wands and nozzles in a designated container or on a pegboard to prevent them from getting lost or damaged. Many pressure washers come with onboard storage for these items, which is an excellent option for keeping everything together.

Pre-Season Inspection and Maintenance

Before bringing your pressure washer out of storage for the season, perform a thorough inspection. Check all hoses for cracks, leaks, or signs of wear. Inspect the spray gun and wand for any blockages or damage. Ensure all connections are tight and secure. For gas models, check the oil level and spark plug. If you used a fuel stabilizer, the fuel should still be good; otherwise, consider draining old fuel and adding fresh. Running clean water through the system before connecting to a power source or starting the engine can help flush out any dust or debris that may have settled during storage.
