As the colder months descend upon us here in Staffordshire, it’s time to start thinking about preparing our garden tools for winter. Among these, the pressure washer is a crucial piece of kit that needs proper attention. Storing it correctly over winter not only extends its lifespan but ensures it’s ready to go when spring arrives.

Quick Answer

To store your pressure washer over winter, drain all water, add antifreeze, and store it in a dry, frost-free place.

Why Proper Storage is Important

Winter in the Midlands can be quite harsh, with temperatures often dipping below freezing. Water left in your pressure washer can freeze, leading to costly damage. By taking a few preventative steps, you can avoid these issues.

Steps to Prepare Your Pressure Washer

1. Drain the Water

Start by disconnecting all hoses and attachments. Run the machine for a few seconds to ensure all water is expelled from the system. This simple step prevents ice from forming inside.

2. Add Antifreeze

Use a pump saver or a mixture of antifreeze to protect the internal components. Inject the antifreeze into the unit according to the manufacturer’s instructions. This will keep the seals and pipes in good condition.

3. Clean the Unit

Give your pressure washer a good clean to remove any dirt or grime. This prevents corrosion and keeps it looking its best. Pay special attention to the nozzle and spray wand.

4. Store in a Suitable Location

Find a dry, frost-free place such as a garage or shed for storage. Ideally, the temperature should remain above freezing to prevent any residual moisture from freezing.

Additional Tips for Pressure Washer Care
