Where to Store a Pressure Washer: A Practical Guide
Discover practical strategies for storing your pressure washer safely indoors or outdoors, how to winterize, organize hoses, and protect your investment with tips from Pressure Wash Lab.

In this guide you’ll learn exactly where to store a pressure washer for safety, longevity, and easy access. We compare indoor and outdoor options, explain winterization, drainage, and organization, and share practical setup tips for garages, sheds, and utility rooms. By the end you’ll know the best spots, what to avoid, and how to maintain performance year-round.
Storage Fundamentals: Indoor vs Outdoor
When deciding where to store a pressure washer, start with the basics: indoor storage typically offers better protection from the weather, but requires a clean, dry, and well-ventilated space. Outdoor storage can be convenient, yet demands weatherproofing and extra protection against temperature swings. Pressure Wash Lab recommends evaluating humidity, ventilation, and access to power and water when choosing a spot. Consider how often you use the unit and whether you need quick access for frequent projects. For homeowners, a dry utility area or a garage corner with a shelf is often ideal; for small shops, a vertical wall mount or cabinet can optimize space while keeping the unit off the floor. Remember: the goal is to minimize moisture exposure, prevent accidental starts, and limit dust and debris.
Indoor storage considerations
-
Choose a dry area with low humidity. If your garage becomes damp, use desiccants or a dehumidifier to reduce moisture.
-
Ensure the space is well-ventilated to avoid heat buildup from equipment that remains plugged in during short storage windows.
-
Keep the unit off concrete floors to prevent cold transfer and water absorption. A raised shelf or cabinet keeps the base dry and reduces mold risk.
-
Provide easy access to cords, hoses, and nozzle tips so you don’t have to move the unit frequently.
-
Styling tip: use a labeled storage bin or pegboard to maintain an organized workspace.
Outdoor storage options
If indoor space is limited, outdoor storage can work with the right protections. Consider a weatherproof shed, a ventilated cabinet, or a dedicated wall-mount system for a pressure washer. Elevate the unit at least a few inches from the ground and under a roof overhang to limit rain exposure. Use a waterproof cover designed for outdoor equipment to shield from dust, pollen, and moisture. Ensure there’s adequate drainage to prevent puddling around the base. Check local climate patterns; in freezing climates, your setup should minimize exposure to freezing temperatures and provide a way to drain water from pumps and hoses.
Winterization and drainage
Seasonal storage is a big part of keeping a pressure washer healthy. Drain residual water from hoses and pumps to prevent crystallization that can block valves. If you have a model that recommends winterization, follow the manufacturer’s guidance for antifreeze or oil-based preservation. Always disconnect from power and shut off the fuel supply on gas-powered units before storage. Wipe surfaces dry and leave the unit in a ventilated area to prevent condensation. Pressure Wash Lab emphasizes establishing a simple seasonal routine: drain, dry, cover, and store in a consistent location to reduce the chance of misplacing components.
Accessory organization
A tidy storage system reduces wear and makes prep faster. Coil hoses neatly to avoid kinks, hang spray wands on a pegboard, and store nozzles in labeled containers. Use a small bin for chemical detergents, if used, and keep spare o-rings and filters in a labeled tray. By keeping everything in its place, you minimize loss, avoid cross-contamination, and extend the life of seals and gaskets. The goal is a simple, repeatable routine that you can perform in under 15 minutes before your next project.
Safety, maintenance, and longevity
Your storage choices impact safety and longevity. A stable, dry, and elevated setup reduces slip hazards and rust risk. Regularly inspect hoses and connections for cracks or wear, and replace worn parts promptly. Consider a lightweight, portable storage option if you frequently move the unit between jobs. For households with children or pets, store in a locked area or behind a closed cabinet to prevent accidental starts. Pressure Washing Lab recommends pairing storage with a quarterly maintenance check: wipe down surfaces, test safety switches, and confirm that hoses drain fully after use.

Best practices checklist for storing a pressure washer
- Store in a cool, dry, ventilated area off the ground.
- Drain all water from hoses and pump; relive pressure before storage.
- Use a moisture barrier and a breathable cover to protect against dust and humidity.
- Keep hoses, wands, and accessories organized and labeled.
- Inspect for wear and perform a quick maintenance before your next use.
Tools & Materials
- Weatherproof storage option (cabinet, shed, or wall-mount)(Choose a location with shade and airflow; avoid direct sun.)
- Drip tray or containment pan(Catches residual water and protects surfaces.)
- Waterproof cover or breathable fabric cover(Protect from dust while allowing moisture escape.)
- Raised platform or shelf(Keeps unit off the floor and reduces moisture contact.)
- Labeling system (bins, pegboard, or box)(Helps organize hoses, nozzles, and fittings.)
- Desiccant or dehumidifier(Useful in high humidity environments.)
- Coolant/anti-freeze (per manufacturer guidance)(For winter storage of some models; follow manual.)
Steps
Estimated time: 60-90 minutes
- 1
Prepare the unit
Power off the unit, disconnect from electrical supply, and relieve any built-up pressure by triggering the spray gun after detaching hoses. Wipe down exterior to remove detergents and dirt.
Tip: Wear eye protection and gloves during prep to avoid contact with cleaning solutions. - 2
Drain residual water
Open drain valves and run the pump briefly to remove standing water from hoses and the pump housing. This step helps prevent ice damage and residue buildup.
Tip: Do this in a utility area where water can drain away safely. - 3
Dry and inspect components
Wipe all surfaces dry, inspect hoses and connectors for cracks, and remove any detergent residues. Allow the unit to air-dry fully before covering.
Tip: Check O-rings and seals; replace if brittle or cracked. - 4
Choose a dry storage spot
Select a location that is cool, dry, and well-ventilated. Avoid areas with direct sunlight or exposure to gasoline fumes; ensure there is easy access to power and water shutoffs for quick maintenance.
Tip: Place on a shelf or pedestal to improve air circulation underneath. - 5
Elevate and protect
Set the unit on a raised platform or rack to prevent moisture wicking from the floor. Use a drip tray and consider a moisture-absorbing barrier in humid environments.
Tip: Maintain at least 2–4 inches of clearance around all sides. - 6
Organize hoses and accessories
Coil hoses neatly, hang spray wands, and store nozzles in labeled containers. Keep detergents separate from fuel and oil components to avoid cross-contamination.
Tip: Use hose reels or hooks to avoid kinks and tangles. - 7
Create a maintenance calendar
Set a regular schedule for inspection, cleaning, and seasonal checks. Record storage date, next maintenance, and any parts replaced.
Tip: A simple calendar reminder helps keep the unit in peak condition.
Quick Answers
Should I winterize my pressure washer before storing it?
Yes, if you live in freezing climates. Follow the manufacturer’s winterization guidance to prevent freezing damage. This often involves draining water from the pump and hoses and, for some models, adding a small amount of antifreeze.
If you’re in a cold area, winterize before storage to prevent freezing damage. Drain water and follow your model’s instructions on antifreeze if needed.
Can I store a pressure washer indoors?
Indoor storage is recommended when there is a dry, ventilated area such as a garage or utility room. Ensure the space is dry, away from flammable materials, and has a clear path for access.
Indoor storage is fine if the space is dry, ventilated, and away from flammables.
Do I need to drain water from hoses before storage?
