Winter Storage: How to Protect Your Power Washer

If your business operates in the north, you are likely nearing your off season as temperatures begin to drop. With that comes putting your power washer in winter storage, but it’s important to properly prepare it first. Here are a few simple steps to ensure your equipment is ready-to-wash once the temperatures warm in the spring.

Winter Storage Tips for Your Power Washer

1. Antifreeze

Follow the Freeze Prevention Tips section for your specific power washer.  Add automotive antifreeze to the float tank. Start your machine and push any remaining water out with antifreeze to ensure that all lines and hoses get coated to protect your unit during storage.

If your unit doesn’t have a float tank, insert the water intake hose into a bucket of antifreeze and proceed with the above steps.

2. Prepare the Fuel Tank

Adding fuel stabilizer to the gas tank will keep your fuel from turning into varnish and will prevent the gaskets in the carburetor from going bad. If you are adding stabilizer, ensure the tank is full to prevent condensation buildup.

Another option is to run the unit until it is out of gas when you will be ending your season.

3. Remove Spark Plugs

Undo the spark plug wires and remove the plugs. Spray WD-40 into the carburetor and the cylinders while turning over the engine to coat everything with oil.

4. Change the Oil

Change the engine oil, oil filter, and fuel filter. If you do not change the engine oil, sludge can collect on the bottom of the oil pan and solidify. If there is any water in the fuel filter, it may freeze and break.

5. Disconnect the Battery

Remove the battery to prevent a slow discharge during storage. Avoid storing the battery in extreme temperatures. Keeping the battery in a dry, room temperature area will prevent condensation and protect battery life. The best place to store equipment is inside an insulated garage or workshop. Come spring, charge on your battery for a couple of hours before use to assure it will have a full charge.

In the spring, put in fresh fuel, replace the spark plugs, and connect the battery. When reconnecting the battery, clean connections and apply grease to prevent corrosion. Start your pressure washer, if it is hard to start, spray WD-40 into the carburetor intake to help fuel flow.
