Winterizing a pressure washer is easy and only takes a few minutes - add fuel stabilizer (for gas powered only), clean out the hose of detergent, disconnect everything and cover your pressure washer and store in a dry place ready for next use.
How to Winterize a Pressure Washer
Winterizing a pressure washer is necessary for two reasons: to protect it against freezing temperatures and prevent the damages that can occur from long periods of inactivity.
The process only takes a few minutes, but it can make the difference between a pressure washer that remains in excellent condition during the winter months and having to replace the washer once spring arrives.
The good news is that winterizing your pressure washer is super simple and super quick, so there is really no excuse not to take this one simple step.
What Could Happen Without Winterization?
Even if you’re just planning to store your pressure washer away for several weeks, winterizing it first is a smart idea. Some of the things that might happen to your pressure washer if you don’t winterize it include:
Keep in mind that gas can go stale in just 30 days, wreaking havoc on your pressure washer and essentially rendering it useless. And since warranties don’t cover pressure washers with damages caused by lack of maintenance, you could lose several hundred dollars or more if you don’t winterize.
If you’re wondering if you should winterize either your gas or electric pressure washer, the answer is that you should winterize both of them. Regardless of where their power comes from, all pressure washers need to be winterized each and every year.
Winterizing Your Gas-Powered Pressure Washer Is Super Easy
Below are some basic steps for winterizing a gas-powered pressure washer. Keep in mind that if the instructions on your pressure washer differ in some way, you should always go by those instructions instead. Here are the basic steps:
Winterizing an Electric Pressure Washer Is Even Easier
Winterizing an electric pressure washer is a piece of cake. It is both faster and simpler than winterizing a gas-powered pressure washer and involves the following steps:
Storing Your Pressure Washer the Right Way
The cover for your pressure washer is important for the winterisation process because it protects it from bugs, spider webs, rust, pests, and, most importantly, moisture. Covers are essential when you have no choice but to keep your pressure washer outside, but even those kept inside of sheds and garages should have well-made covers.
If possible, buy a cover made out of some type of cloth, such as polyester or canvas, with a water-resistant or waterproof coating. Covers can be either water-repelling, water-resistant, or waterproof. Of course, the waterproof ones work best, but you can use other ones if you can’t find those.
You can take measurements of your pressure washer before you shop for a cover, but many of these covers are one-size-fits-all, and therefore, that may not be necessary. If you absolutely cannot find a cover you like, cover the pressure washer with a barbecue grill cover or even a tarp.
A cover that isn’t made specifically for pressure washers and other tools will always be better than no cover at all, especially if you plan to store your pressure washer outside exposed to the elements.
Winterizing your pressure washer is crucial, and the main thing you need to remember is to make sure that your washer is completely drained of all fluids before storing it away for the winter.
Even small amounts of moisture can wreak havoc on your pressure washer, and adding the stabilizer and antifreeze is just as important. Remember that the cold temperatures and the idleness of the pressure washer are its biggest enemies this time of year.
Fortunately, it usually takes only a few minutes to complete the winterization process for both gas-powered and electric pressure washers, but it saves you a lot of money and many headaches in the long run, every time.
