Quick answer
Before winter, pressure wash the things that will sit dirty for months: patio furniture, decks, concrete walkways, trash bins and your car. Pick a mild day above 40°F with no overnight freeze in the forecast. Start with the widest spray (40°), stay about 12 inches back, and let everything dry for a day before you cover or store it. A cordless washer such as the KingFurt 6-in-1 power washer draws water from a bucket, so it still works after you've shut off the outdoor faucet. Kits start at $59.99.
The leaves are mostly down, the patio set is about to go under covers, and the to-do list is getting longer. There's a reason pressure-washing videos rack up millions of views: watching a dull gray paver turn back to its real color is oddly calming. It feels even better when it's your own patio.
So grab a free afternoon before the first hard freeze and pressure wash away a little stress. Here's what to clean, which nozzle to use, and how to put your washer away so it's ready for spring.
Fall pressure-washing checklist at a glance
| What to clean | Why do it before winter | Nozzle |
|---|---|---|
| Patio furniture | Wash off summer grime before it goes under a cover | 40° (25° for metal) |
| Deck and wood steps | Algae makes boards slick once it gets wet and cold | 40°, never 0° |
| Concrete patio and walkways | Leaf stains set into concrete over winter | 25° or 15° |
| Garage door and entry | Removes spider webs and dust before the door closes up for winter | 40° |
| Trash and recycling bins | Smells don't freeze away | 25° |
| Car, wheels and wheel wells | Starts winter clean before road salt arrives | 40° plus foam |
| Bikes and kids' outdoor toys | Mud dries hard if they're stored dirty | 40° |
01Why pressure wash in the fall?
Spring gets all the cleaning attention, but fall is the smarter time for most outdoor surfaces:
- Dirt sits all winter. Pollen, bird droppings and wet leaves left on furniture and concrete for four months stain far more than they would in one.
- Slippery surfaces get worse. Algae and mildew on decks and steps turn slick once they're wet and cold.
- Covers trap what's underneath. Putting a cover over dirty, damp furniture is the fastest way to grow mildew.
- Spring is easier. Clean now, and the first warm weekend of the year is for enjoying the patio, not scrubbing it.
02What should you pressure wash before winter?
Start with whatever bugs you most every time you walk past it. Then work through the rest of this list.
Around the house
- Front steps and entry
- Garage door and garage floor
- Concrete walkways and the driveway apron
- Trash and recycling bins
- Window screens (use the 40° spray and stand well back)
Outdoor living
- Patio furniture frames and umbrella bases
- Deck boards and railings
- Pavers and the patio slab
- Planters and plant stands you're bringing inside
- Swing sets and outdoor toys
Vehicles and gear
- Car body, wheels and wheel wells
- Bikes, scooters and strollers
- Lawn mower deck (battery removed or engine off and cool)
- Garden tools before they go on the wall for winter
03Which pressure washer nozzle should you use?
The angle on the nozzle is the width of the spray. A narrower spray hits harder on a smaller spot. When in doubt, start wide and move in.
| Spray | What it does | Use it for |
|---|---|---|
| 0° (red) | Pencil-thin, most concentrated | Stuck-on mud in small spots on concrete. Never on wood, paint, screens, skin or pets. |
| 15° (yellow) | Narrow fan for scraping | Concrete stains, paver joints, metal furniture legs |
| 25° (green) | All-purpose fan | Walkways, bins, plastic furniture, fences |
| 40° (white) | Wide, gentle fan | Cars, decks, windows, garage doors, anything painted |
| Foam / soap | Low-pressure soap application | Pre-soaking cars and greasy surfaces before rinsing |
04Is a cordless pressure washer powerful enough?
For most fall clean-up, yes. A cordless pressure washer isn't a 3,000 PSI gas machine, and it doesn't need to be. It's built for the jobs most people actually do: cars, patio furniture, bikes, bins, fences, steps and spot-cleaning concrete. If you need to strip paint or lift years of oil stains from a whole driveway, rent a gas washer for the day.
What a cordless model does better is show up. There's no extension cord, no gas, and no hunting for a spigot. Both of our kits pull water from a bucket, a rain barrel or a pond through their own hose and filter. In late fall, when you've already shut off and drained the outdoor faucet, that matters.

05How do you pressure wash a patio or deck, step by step?
- Clear the area. Move furniture, planters and doormats. Blow off leaves and grit first with a cordless leaf blower; wet leaves are much harder to move.
- Cover what shouldn't get wet. Outdoor outlets, light fixtures and nearby plants.
- Fill your bucket and connect the hose. Drop the filter end in the water so it stays submerged.
- Pre-soak with foam if it's greasy. Let it sit a few minutes, but don't let it dry.
- Wash with the wide spray. Start at 40°, work in overlapping strips, and go with the grain on wood. Move to 25° only if the dirt isn't moving.
- Detail by hand. Grout lines, corners and window tracks are faster with a spin scrubber than with a narrow spray.
- Rinse and let it dry. Give furniture and decks at least 24 hours before covering or sealing.
06What should you do after washing?
Protect the work you just did. Once everything is dry, cover the furniture you leave outside and put away the rest. Our patio covers have buckle straps and drawstrings, so they stay on through wind. Prop up the middle of the table cover with something small so rain runs off instead of pooling.

07How do you store a cordless pressure washer for winter?
Water left inside the pump can freeze, expand and crack it. Before you put it away:
- Disconnect the hose and filter, then let water drain out of the washer, the hose and the nozzle.
- Wipe the unit dry and clean the inlet filter of sand and leaves.
- Store the washer indoors where it stays above freezing, such as a heated garage, basement or closet, not in an outdoor shed.
- Take the batteries out and store them indoors at room temperature. Follow the manual for charging before long storage.
- Keep the hose loosely coiled so it doesn't crack in the cold.
Now it's your turn
Pick one spot this weekend, from the steps to the patio set to the car, and enjoy the before-and-after.
