How to Store a Power Washer
Nov 4, 2025 / Public Storage
You can store a power washer in a storage unit by cleaning it thoroughly, draining all fluids, and stashing it in a dry spot until its next use. Doing this keeps your machine ready for action and helps you declutter your garage.
Give Your Power Washer a Thorough Cleaning
Before packing it away, give your power washer a proper wash. If it’s been recently used, let your washer cool down before you begin to put it away. Spray down the exterior to remove dirt, mud, and grim, paying close attention to the nozzle and hose. Wipe down any metal parts to prevent corrosion. Not only does this make the machine look neat, but it also prevents buildup that can affect performance the next time you fire it up.
Drain Fluids and Prep the Engine
Gas-powered power washers hold fuel and oil that can gum up the engine if left sitting and cannot be stored at Public Storage. Drain the gas tank completely or run the engine until it’s empty outside and a safe distance away from any units. Change the oil if it’s due and remove the spark plug.
Electric models are easier to manage. They mainly need to be unplugged and kept dry, but a wipe down ensures no dust or moisture settles in the unit.
For both types, disconnect the hose from both the spray gun and the high-pressure outlet on the pump. Let any leftover water drain out from the hose, spray gun, and lance, Then, give each piece a quick wipe-down with a rag. After that, empty any remaining liquids from the pump so your power washer is ready for storage.
How Should You Organize Your Storage Space?
Pick a spot in your unit where your power washer can sit off the floor, ideally on a pallet or mat. This keeps it away from any potential dampness and makes it easier to access. Coil hoses neatly, and place small accessories, like nozzles and spray guns, in labeled bins.
Cover It Up
Covering your power washer with a lightweight tarp or breathable cloth helps keep dust off. Avoid heavy plastic that can trap moisture, which could lead to rust over time. For long-term storage, check in occasionally to make sure everything is dry and in place.
Extra Tips for Hassle-Free Storage
- Keep cords and hoses coiled separately to avoid tangles.
- Store smaller parts in clear bins for easy access.
- Consider a climate-controlled unit if you’re storing your power washer for months, as this helps reduce humidity exposure.
- If possible, label each bin with its contents to make retrieval a breeze.

Features and amenities vary by location, facility, and unit. “Climate-controlled” and related terms (such as air-conditioned, heated, or humidistat-equipped) describe storage spaces designed to help maintain more consistent temperature or humidity levels compared to non-climate-controlled units. Public Storage does not guarantee temperature or humidity ranges. Availability, features, and unit types may differ by location, facility, and unit. Please confirm with your facility whether specific climate-controlled features are available on units at that location.
