These are the three easy steps to Winterize Your Electric Pressure Washer:
- An electrical machine has no internal combustion engine you simply got to map out the pump system for storage.
- Start by getting a bucket of water and place the detergent suction hose in it. Attach the hose and switch the faucet on.

Where to Store It?
The safest place to store your pressure washer is in a dry and heated spot, preferably in your home garage or basement.
How to Use Pump Saver
Specific directions will depend upon which brand of electric pressure washer you are using, but all of them require you to connect the bottle to the water inlet (where you attach the garden hose).
Generally, you’ll squash the bottle. Pull the starter string about 3 or 5 times (using about ⅓ of the bottle or can). This pulls the pump saver through the pump system until you see it flowing from the water outlet.
For an electrical pressure washer, just keep squeezing the bottle or trigger until the fluid flows from the outlet.
Don’t Forget the Cover!
Storage covers protect your pressure washer from bugs, dust, moisture, spider webs, mice, and rust. If you want to keep your pressure washer outside for whatever reason, you need to save from the sun and rain, not to mention bird poop.
Covers made from cloth (often canvas or polyester) with a water-resistant coating like polyethylene allow them to breathe while protecting from moisture damage.
They can be water-repelling or waterproof. Of course, if you’re storing outdoors, the more waterproof the cove is, the higher the protection will be.
Many covers are a one-size-fits-all deal, but it won’t hurt to require measurements just to match. You would like a cozy enough fit without it leaving anything exposed. A canvas or BBQ grill cover can work with a few adjustments.

I grew up on a small farm in New Jersey. We had a big family because my parents, my uncles, and aunties all were living together on this farm so, you can imagine, it was always overcrowded with people. We built our first home from scratch (of course I and my husband both have a degree in interior designing from Syracuse University) but still, I know so many of our classmates wouldn’t bother doing it themselves and rather delegate it to some agency or person but we both are crazy about our passion.
