As the colder months approach, it’s important to properly store your pressure washer to avoid damage and ensure it will be in good working condition when you need it again. Pressure washers, like most outdoor equipment, require care and attention during the off-season. Storing a pressure washer for the winter is not just about finding a place to store it; it involves cleaning, draining, and protecting vital components to avoid costly repairs and maintenance issues when spring arrives.
In this article, we will walk you through the essential steps to store your pressure washer properly for the winter.
Why Proper Storage is Essential
Before diving into the specific steps, it’s important to understand why proper storage is crucial. A pressure washer is a complex piece of machinery with a water pump, engine, and various seals and hoses that can be vulnerable to cold temperatures and moisture. If left unprotected, these components can freeze, crack, or degrade over time. Additionally, any residual fuel or water left in the system can deteriorate, leading to poor performance or even permanent damage.
Taking the time to properly store your pressure washer will help protect its internal parts and ensure it starts up and functions effectively when the weather improves.
Step 1: Clean the Pressure Washer
Cleaning your pressure washer is the first step in preparing it for winter storage. Dirt, grime, and debris can accumulate on both the exterior and interior components of the machine during use. Leaving this dirt behind can lead to clogs and damage.
Clean the Exterior
Start by wiping down the exterior of the pressure washer with a damp cloth. Clean the surface to remove dust, dirt, and any other debris that could cause wear over time. Pay attention to the water inlet, nozzle, and wand as these areas tend to collect dirt and are essential for maintaining proper water flow.
Clean the Hose and Nozzle
Next, clean the pressure washer hose and nozzle. The hose should be free of debris and kinks that could cause blockages or damage. Detach the hose from the pressure washer and spray gun, then rinse it out with water. Afterward, allow the hose to dry completely before storing it. Remove the nozzle from the wand and clean it to ensure it’s free of dirt or blockages.
Step 2: Drain the Water System
One of the most important steps in winterizing your pressure washer is to drain the water system. If water is left inside the pump, hose, or nozzle, it can freeze and cause serious damage. Frozen water can lead to cracked pipes, hoses, or even a ruined pump.
Release the Pressure
Before draining the system, release any remaining pressure from the pressure washer. Pull the trigger on the spray gun to let the water flow out and relieve the built-up pressure. This step ensures that no water is left under pressure, which could lead to damage when freezing temperatures hit.
Drain the Pump and Hoses
Once the pressure is released, disconnect the hose from the pressure washer and remove the spray gun. Let any remaining water drain from the pump and hoses. Some pressure washers have built-in drain valves that make this step easier. If your model doesn’t have a drain valve, simply tilt the unit to allow water to escape.
Step 3: Empty the Fuel Tank (For Gas-Powered Pressure Washers)
If you have a gas-powered pressure washer, it’s important to empty the fuel tank before storing the machine. Gasoline can deteriorate over time, leading to gum and varnish deposits that can clog the engine and fuel lines. This can make it difficult for the pressure washer to start or function properly in the future.
Option 1: Use a Fuel Stabilizer
If you don’t want to drain the entire fuel tank, you can use a fuel stabilizer. Fuel stabilizers help preserve gasoline for longer periods by preventing oxidation and degradation. Add the stabilizer to the fuel tank according to the manufacturer’s instructions, then run the engine for a few minutes to ensure the stabilized fuel reaches the carburetor and other engine components.
Option 2: Drain the Fuel Tank
If you prefer not to use a stabilizer, it’s best to drain the fuel tank completely. Start the engine and let it run until all the gasoline has been used up. Once the fuel tank is empty, turn off the engine and store the pressure washer in a cool, dry place.
Step 4: Check the Oil (For Gas-Powered Pressure Washers)
For gas-powered pressure washers, checking the oil is an essential step. Over time, engine oil can degrade and become less effective at lubricating the engine. Before storing the pressure washer, check the oil level and quality.
Change the Oil if Necessary
If the oil appears dirty or contaminated, it’s a good idea to change it before storage. Fresh oil will ensure that the engine stays lubricated and in good condition during the winter months. Follow the manufacturer’s guidelines for changing the oil, and be sure to dispose of the used oil in an environmentally responsible manner.
Step 5: Store the Pressure Washer in a Dry Location
After cleaning and draining the pressure washer, it’s time to store it. Proper storage is key to protecting the machine from damage caused by cold temperatures, moisture, and pests.
Choose a Cool, Dry Area
The ideal place to store your pressure washer is in a cool, dry environment. A garage or shed is an excellent choice. Avoid storing the pressure washer outside or in an area where temperatures may drop below freezing. Exposure to freezing temperatures can cause internal parts, such as rubber seals and gaskets, to crack and fail. Additionally, storing the pressure washer in an overly damp environment could cause rust and corrosion.
Keep It Elevated
To avoid any potential damage from dirt, moisture, or pests, store the pressure washer off the ground. Placing it on a shelf or stand will keep it safe and ensure it is well-ventilated. This also prevents the pressure washer from coming into contact with floor moisture that could lead to rust.
Step 6: Use a Protective Cover
A protective cover can help safeguard your pressure washer from dust, dirt, and pests during the off-season. While this step is not strictly necessary, it provides an extra layer of protection that can help keep your machine in optimal condition.
Choose the Right Cover
When selecting a cover for your pressure washer, make sure it fits the model properly. A cover made from durable, weather-resistant material will help keep out dust and moisture, and it will shield the machine from debris. Be sure the cover is secure and doesn’t allow any moisture to seep in.
Step 7: Regular Maintenance
Even while the pressure washer is in storage, it’s important to regularly check on it to ensure it remains in good condition. Every few months, take a moment to inspect the machine for any signs of damage, such as rust, cracks, or pests. Also, check the oil levels and ensure that the cover is still in place and secure.
Conclusion
Properly storing your pressure washer for the winter months is essential to ensuring that it remains in good condition and is ready for use when the weather improves. By following these steps—cleaning the machine, draining the water system and fuel tank, checking the oil, and storing it in a dry, cool place—you can prolong the life of your pressure washer and avoid costly repairs. A little time spent on winterizing your pressure washer now can save you time, money, and frustration in the long run.
