Restoring the original look of your patio or driveway often means wrestling with a pressure washer wand, chasing stubborn dirt in a hunchbacked position while muddy water splashes back onto your clothes. The process is physically draining, time-consuming, and frequently leaves behind unsightly streaks. A proper solution targets the specific challenges of cleaning interlocking stone and concrete slabs without the mess.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve studied dozens of formulations and attachments, comparing their real-world cleaning power against the specific demands of paver stone maintenance, analyzing hundreds of owner reports to separate marketing claims from genuine results.
This guide examines the most effective options available today, from concentrated degreasers to surface cleaner attachments, so you can make an informed choice. Whether you need a powerful attachment to strip years of grime or a gentle sealer to prevent regrowth, the market has a tool tailored to your surface. Read on to find the best paver cleaner for your specific cleaning challenge.
How To Choose The Best Paver Cleaner
Pavers are porous and easily trap oil, algae, and dirt deep within their surface. Choosing the right cleaner depends on understanding the nature of the stain, the tool you’ll use to apply pressure, and whether you’re cleaning or sealing. The wrong product can leave a chalky residue, strip sealer, or fail to penetrate old stains.
Match the Cleaner to the Stain Type
Oil and grease require a degreaser or a bio-remediation powder that breaks down hydrocarbons over time. General dirt and algae respond better to a surface cleaner attachment that uses high-pressure spinning jets to lift grime without harsh chemicals. Using a general degreaser on mildew may be ineffective, while a pressure washer alone often fails on set-in oil spots.
Understand Your Pressure Washer’s Flow Rate
A surface cleaner attachment needs sufficient water volume (GPM) and pressure (PSI) to spin the jets effectively. A unit rated for 2.0 GPM or less will struggle to clean large areas, while an attachment rated for 4.0 GPM can handle heavy commercial use. Always check that your washer’s output falls within the attachment’s recommended range to avoid weak cleaning or damage.
Decide Between Mechanical and Chemical Cleaning
Mechanical cleaners (surface cleaner attachments) remove surface grime quickly and are ideal for routine maintenance. Chemical cleaners (degreasers, bio-remediation powders) penetrate the paver’s pores to lift embedded oil and organic stains. For heavily stained driveways, a two-step process—apply a chemical pre-treatment, then use a surface cleaner—produces the best results.

In‑Depth Reviews
1. MEKOH 16.5″ Surface Cleaner
The MEKOH 16.5″ Surface Cleaner is the quintessential mid-range winner that transforms a back-breaking Saturday chore into a manageable two-hour job. Its lightweight 6-pound body glides smoothly on four caster wheels, eliminating the need to hunch over a wand and allowing you to stand upright while working. Owners report cutting cleaning time by 75% while achieving a streakless finish on concrete, brick, and pavers.
The splash-resistant skirt traps muddy water and grime inside, so you stay dry and your work area stays neat. The dual spinning jets create a uniform cleaning pattern that prevents the zebra-striping effect common with wand attachments. It connects to most electric and gas pressure washers ranging from 2300 to 3600 PSI using a universal 1/4-inch quick-connect, and it requires no assembly out of the box.
Long-term durability is supported by a housing tested to survive 20-plus drops and stainless steel components that resist corrosion. While the plastic housing raises questions about longevity for heavy commercial use, the overwhelming majority of owners report excellent results for residential driveways, sidewalks, and patios. For the price, this is the most effective pairing of speed and finish quality.
What works
- Reduces cleaning time by roughly 75% compared to wand
- Splash skirt keeps user dry and minimizes mess
- No assembly required, works straight out of box
- Lightweight and easy to maneuver on flat surfaces
What doesn’t
- Plastic housing may not withstand heavy commercial daily use
- Extension wand not included
2. ACT Concrete Cleaner – Eco-Friendly Dry Powder
The ACT Concrete Cleaner takes a fundamentally different approach to paver cleaning: it uses live microbes to digest oil and grease stains. This bio-remediation powder is applied dry to the spot, misted with water, and left to work for two to four weeks. It is non-toxic, safe around pets and plants, and HOA-approved, making it an excellent choice for homeowners who want to avoid harsh chemicals.
Owners report that it removes 90% of old oil stains where pressure washing failed. The microbes break down the hydrocarbons into CO2, hydrogen, and oxygen, leaving the concrete stronger and the stain gone. It works in temperatures from sub-zero to over 200 degrees and requires no pressure washing, no bleach, and no scrubbing. One pound covers 100 square feet, and the powder covers the stain from view during the digestion process.
The primary limitation is time: it requires patience, and results on very old, set-in stains can be mixed. The powder leaves a white chalky residue that needs cleanup, and it is not a quick fix for large surface areas. It works best on fresh oil spots and as a follow-up treatment after mechanical cleaning for stubborn embedded oil.
What works
- Effectively removes oil stains where pressure washing fails
- Non-toxic, safe for pets, plants, and people
- Works in extreme temperatures and on various surfaces
- HOA approved and eco-friendly
What doesn’t
- Takes 2-4 weeks for full results
- Leaves chalky white residue needing careful cleanup
- Less effective on deeply embedded old stains
3. Zep Driveway, Masonry and Concrete Cleaner and Degreaser
The Zep Driveway and Concrete Cleaner is a construction-grade degreaser concentrate designed for professionals who need to remove tire marks, oil, grease, and heavy grime from concrete, brick, asphalt, and pavers. It comes in a case of four one-gallon jugs, making it a cost-effective choice for large-scale cleaning projects or commercial use. Owners report that it successfully cleaned two-year-old garage floor grime and a stubborn greasy grill spill that other cleaners couldn’t touch.
The formula is applied with a mop or pump sprayer, scrubbed in, and rinsed after no more than ten minutes of contact time. For older or larger stains, a pre-treatment before full surface cleaning is recommended. The concentrate allows you to adjust strength for different stain levels, and it works well as a pre-soak before pressure washing to break down tough deposits.
Some users found it less effective on extremely deeply embedded dirt and wished for more cleaning power. The 10-minute contact window requires brisk work on large areas, and the concentrated formula requires careful dilution. For homeowners dealing with heavy oil spots or professional contractors needing a reliable workhorse, this Zep product delivers consistent results.
What works
- Construction-grade formula handles heavy grease and oil
- Concentrated, covers large areas cost-effectively
- Effective on brick, asphalt, concrete, and pavers
What doesn’t
- Results vary on very old, deeply set stains
- Requires quick work within 10-minute contact window
4. MasonryDefender Patio Paver Sealer
While not a traditional cleaner, the MasonryDefender Patio Paver Sealer plays a critical role in maintaining clean pavers by sealing joints and locking sand in place. This water-based acrylic sealer dries clear with a low gloss finish, providing waterproof protection without a slippery surface. Owners who apply it every other year report that it hardens polymerized sand, preventing weed growth and ant colonization between pavers.
It covers 75 to 150 square feet per gallon and can be applied with a pump-up sprayer followed by a back brush. It dries in one to two hours between coats, and cleanup is simple with soap and water. The low odor and VOC-compliant formula make it suitable for residential use around occupied spaces.
The sealer is not a stain remover; it is a protective coating applied after cleaning. It works best on horizontal stone, clay brick, and concrete pavers. Some owners note that the price per gallon is on the high side, but the results—a beautiful matte finish that locks everything in place—are consistently described as worth the investment for those who want long-term paver preservation.
What works
- Hardens joint sand and prevents weed growth
- Dries clear with a non-slippery low gloss finish
- Low odor and easy water-based cleanup
What doesn’t
- Not a cleaner; must be applied after thorough washing
- Price per gallon is higher than some alternatives
5. MEKOH Pressure Washer Surface Cleaner 20″
The MEKOH 20″ Surface Cleaner is the premium, large-area workhorse for those with commercial-grade pressure washers. Its 20-inch cleaning path and twin high-pressure spinning nozzles cover ground eight times faster than a standard wand, making it ideal for long driveways, curbs, and expansive patios. It is rated for up to 4500 PSI and 4.0 GPM, placing it firmly in the professional category.
Owners transitioning from smaller Ryobi or similar attachments describe the difference as night and day. The unit features two angle-adjustable handles and four smooth-rolling casters that allow effortless back-and-forth gliding. The fully sealed brass bearing prevents leaks, and the changeable nozzles allow you to switch between power washing and soft washing patterns for different surface types.
At roughly 17 pounds, it is heavier than smaller models but still manageable for a full-day cleaning job. One improvement noted by users is the handle’s tendency to flop when stored; a locking mechanism would be welcomed. For heavy residential use or commercial applications where speed and cleaning width matter most, this surface cleaner delivers professional results without the professional price tag.
What works
- 20-inch cleaning path significantly speeds up large area jobs
- Handles up to 4500 PSI and 4.0 GPM
- Adjustable handles and smooth casters reduce user fatigue
- Changeable nozzles for power and soft washing
What doesn’t
- Handle lacks locking mechanism, flops when stored
- Heavier than smaller surface cleaners
Hardware & Specs Guide
PSI and GPM Matching
A surface cleaner needs a pressure washer that delivers both sufficient pressure and water flow. Most residential attachments require at least 2.0 GPM and 2300 PSI to spin the jets properly. Using an attachment below the minimum flow rate results in weak jet rotation and uneven cleaning. The MEKOH 16.5″ works from 2300 to 3600 PSI, while the 20″ model requires a higher output for maximum efficiency.
Chemical vs. Mechanical Timelines
Mechanical surface cleaners provide instant results suitable for routine maintenance and large area jobs. Chemical cleaners like the ACT bio-remediation powder work on a longer timeline—typically two to four weeks—to break down oil at the molecular level. For the most stubborn oil stains, a two-phase approach using a degreaser (like Zep) followed by mechanical cleaning with a surface cleaner yields the best results.
