Pressure Washer Attachments That Actually Blasted Moss Off My Patio Stones
30
items Spent two summers scrubbing patio stones on my hands and knees with a brush and bleach, getting nowhere. The moss kept coming back thicker. If you've got green slime creeping across your walkway and you're tired of renting equipment or paying someone...

Surface Cleaner Attachments for Patio Stone
Dragging a regular pressure washer wand across flagstone left tiger stripes everywhere. Looked worse than the moss. A surface cleaner changed everything because it spins evenly and you just walk behind it like mowing a lawn.
Grab this if your patio is under 300 square feet. I did my entire back patio in about 40 minutes, and the difference between the cleaned half and the dirty half made my neighbor walk over and ask what I was using.
Greenworks 12 in Surface Cleaner Pressure Washer
Use this for bigger jobs. My driveway is about 600 square feet of concrete pavers and this knocked it out in one afternoon. The dual nozzle setup underneath means fewer missed spots and no streaking.
Simpson, Surface Cleaner, 15 Inch, Universal 3700 PSI
Perfect if you already own a Ryobi electric unit. Snaps right on, no adapter needed. I was skeptical an electric could handle moss but it peeled off layers I didn't even know were there.
12 in. 2300 PSI Electric Pressure Washers Surface Cleaner
Try this if you've got a gas washer and want something that fits without fiddling with adapters for 20 minutes. Rolled it across my sandstone path and the original color came back like it was just installed.
Westinghouse, Surface Cleaner, 15", 3400 PSI, ¼" Connector
Keep this one around for smaller sections like front steps or a side walkway. It's lightweight enough that my wife uses it without getting tired, and it cleaned the moss off our front landing in about five minutes flat.
Sun Joe Pressure Washer Accessory, SPX-PCA10
Switch to this if you need something that handles higher PSI without wobbling. I cranked mine up to 3000 PSI on a really stubborn section near our garden wall and it didn't skip or stall once.
Briggs & Stratton 14 Inch Rotating Surface Cleaner
Turbo Nozzles for Stubborn Moss Patches
Some corners and crevices between stones hold onto moss like it's paying rent. A turbo nozzle concentrates the spray into a spinning point that digs into grout lines and rough surfaces where a flat cleaner can't reach.
Grab this for the joints between pavers where moss roots dig in deep. I spent ten minutes on a section that my regular nozzle couldn't touch, and the turbo tip ripped it clean. Stock up because the o-ring wears out after heavy use.
Hyper Tough Turbo Nozzle Pressure Washer 3600 PSI
Use this when you've got a thick mat of green growing in shaded corners. Pointed it at the worst spot behind my shed and watched moss fly off in chunks. For anyone who thought that corner was permanently green.
Hyper Tough Turbo Nozzle Pressure Washer 3600 PSI
Swap your fan tip for this when you hit a stubborn patch. The rotating jet covers more area than a zero-degree tip but still has enough punch to blast through moss that's been growing for years.
Hyper Tough Turbo Nozzle Pressure Washer 3600 PSI
Keep this in your toolkit for the really gnarly stuff. My back wall retaining stones had a solid inch of moss buildup and this cut through it like I was peeling a sticker off glass.
STYDDI Pressure Washer Tips Nozzles, 7 Pack
Try this if your current turbo tip keeps disconnecting under pressure. The quick-connect on this one actually stays locked. Used it for two hours straight on my walkway without a single pop-off.
Hyper Tough Turbo Nozzle Pressure Washer 3600 PSI
For anyone running a gas washer who needs serious power in tight spots. I used this along the edges where my patio meets the garden bed, and it cleaned a line so crisp it looked like I used a ruler.
Hyper Tough Turbo Nozzle Pressure Washer 3600 PSI
Pressure Washer Detergents and Moss Killers
Water alone gets 80% of the job done, but the moss grows right back within weeks. Running a detergent through the low-pressure soap nozzle first loosens everything and kills the roots so you're not redoing this every month.
Spray this on the night before you pressure wash and the moss practically surrenders. I applied it to my worst section on a Thursday evening, washed Saturday morning, and the stones looked brand new. Wish I'd found this two years ago.
Wet & Forget Outdoor Moss, Mold, Mildew, and Algae Stain
Toss this in your downstream injector and let it sit for five minutes before you blast. Works on concrete, brick, and natural stone. My neighbor borrowed it for his retaining wall and called me the next day saying he couldn't believe the difference.
30 SECONDS Outdoor Cleaner, Concrete, 2pk
Use this if you want something you can also spray on siding and fences while you've got the washer out. Did my entire patio and the north side of my house in one session. Two birds, one bottle.
Mold Armor E-Z House Wash, 64 oz., Brick, Concrete
For anyone worried about killing the plants next to the patio. This one is biodegradable and I sprayed it right next to my hostas without any damage. The moss still came off clean, no compromises.
Simple Green Oxy Solve Total Outdoor Pressure Washer Cleaner
Pair this with a surface cleaner attachment and watch oil stains and moss come off at the same time. My garage apron had both problems and one pass handled everything. Dilutes pretty far so one jug lasts multiple sessions.
Zep Driveway and Concrete Pressure Wash Cleaner Concentrate
Grab this if you want a cleaner that foams up so you can actually see where you've applied it. Sprayed my entire patio, watched the foam turn brown as it lifted the grime, then rinsed. Deeply satisfying to watch.
Scotts, Outdoor Cleaner Plus OxiClean Refill Concentrate
Pressure Washers That Handle Patio Jobs
Had an old 1400 PSI electric unit that couldn't handle moss on textured stone. It was like trying to scrub a cast iron pan with a wet napkin. Upgraded and the difference was night and day.
Try this if you want electric but with actual power. Quiet enough to use on a Sunday morning without your neighbors hating you, but strong enough to strip moss off flagstone in a single pass. Stored it upright in my garage, barely takes up space.
2300 PSI Electric Pressure Washers & Power Washers(20)
Perfect entry point if you've never owned a pressure washer. Two detergent tanks so you can run soap first and rinse second without stopping. Cleaned my 200 square foot patio on the first try.
Sun Joe, Electric Pressure Washer, 2030 PSI, 1.2 GPM
For anyone with a large property or commercial-grade moss problems. This thing is serious. Did my entire patio, driveway, and sidewalk on half a tank of gas. Overkill for a small space, but if you've got acreage, this is the one.
Westinghouse 3400-PSI, 2.6-GPM Gas Pressure Washer
Bring this out when you've got years of neglect to undo. Bought it after inheriting a house where the patio hadn't been cleaned in a decade. Three hours and the whole thing looked like fresh stone.
Simpson Cleaning MegaShot 3300 PSI 2.4 GPM Pressure
Keep this around for regular maintenance washes once you've done the big initial clean. Light, easy to drag around, and enough pressure to knock off new moss growth before it gets established.
Greenworks Electric Pressure Washers
Snag this if you want the Honda engine reliability without the commercial price tag. Ran mine for four hours straight on a rental property cleanout. Started on the first pull every time, which is more than I can say for my old one.
Carburetor For Ryobi 3100 PSI Pressure Washer Honda
Accessories That Make the Job Faster
Learned the hard way that the right hose, extension wand, and safety gear save you time and back pain. First time I pressure washed, I was hunched over for three hours and could barely move the next day.
Ditch whatever stiff rubber hose came with your washer. This one stays flexible even in cold weather and doesn't kink when you walk around corners. Did my whole patio without stopping to untangle once.
Flexzilla® Pressure Washer Hose, 5/16" x 25'
Use this so you're not bent over like a question mark the whole time. Added it to my wand and could stand completely upright while cleaning. My lower back thanked me for about a week afterward.
DUSICHIN Short Pressure Washer Wand High Spray Gun 5 Nozzle Tips
Swap out the cheap trigger gun that came in the box. This one has a real comfortable grip and the trigger doesn't make your hand cramp after 20 minutes. Small upgrade that makes a huge difference on long jobs.
Apache 5/16" 3700 psi Thermoplastic Pressure Washer
Wear these. Not optional. First time I pressure washed moss, a chunk flew up and hit me right below the eye. Could have been a lot worse. These stay clear even when it's humid and misty from the spray.
EyeArmor+ Anti-Fog In-Out Safety Glasses
Throw these on before you start because you WILL get soaked from the knees down. I ruined a pair of jeans and shoes my first time out. Now I suit up in these and stay dry the entire session.
Carhartt Men's Lightweight Rain Storm Bib Overall
Sounds weird but measure your patio before you buy a surface cleaner. I bought a 15-inch cleaner for a 6-foot wide walkway and wished I'd gone smaller. Five minutes of measuring saves you a return trip.
