Cleaning exterior brick and paver surfaces with a pressure washer alone often leaves behind stubborn stains like efflorescence, tire marks, and deep-set grime. The right chemical solution breaks that bond, allowing water pressure to restore a surface without aggressive scrubbing or acid damage.
I’m Rikta — the co-founder and writer behind FitlyFast. I’ve analyzed dozens of masonry cleaning formulas, comparing their chemical makeup, dilution ratios, and real-world stain removal performance to compile this guide.
A dedicated brick cleaner for pressure washer uses surfactants and degreasers that lift organic stains and oil from porous surfaces, making your rinse cycle dramatically more effective.
How To Choose The Best Brick Cleaner For Pressure Washer
Brick and paver cleaners vary widely in chemical base, concentration, and surface safety. A wrong choice can etch your stone, kill surrounding grass, or leave a white residue. Focus on these three factors.
Acid vs. Acid-Free Formulas
Acid-based cleaners (muriatic acid) remove efflorescence fast but can etch soft brick and harm vegetation. Acid-free alternatives use surfactants and butyl technology that lift stains without etching, making them safer for residential use around lawns and flower beds.
Concentration and Dilution Ratio
Concentrated formulas cost more upfront but often yield up to 20 gallons of ready-to-use cleaner per gallon of concentrate. A high concentrate gives you flexibility — use it full-strength for oil stains or dilute for routine moss and dirt removal.
Pressure Washer Compatibility
Some cleaners are designed for downstream injectors and foam cannons, while others work best with pump sprayers. Check if the formula is free-rinsing to avoid streaking, and confirm it won’t clog your pressure washer nozzle.

In‑Depth Reviews
1. RadonSeal BrickTastic Brick & Paver Cleaner
The RadonSeal BrickTastic uses advanced butyl technology and proprietary surfactants to lift leaf stains, soot, carbon, oil, creosote, and tire marks without any acid. Its concentrated formula creates up to 20 gallons of ready-to-use solution from a single gallon, making it one of the most economical choices for large brick and paver projects.
Users report excellent results on fireplace brick, paver driveways, and brick homes, with many noting the absence of toxic smell and the safe rinsing properties around grass and plants. The free-rinsing formula leaves no streaky residue, which is critical when using a pressure washer to avoid blotchy surfaces.
While a few customers experienced limited results on heavily embedded stains, the overwhelming feedback highlights its versatility across indoor and outdoor masonry. The non-abrasive, acid-free chemistry makes it a safe first choice for homeowners who want to clean without risking surface etching.
Why it’s great
- One gallon makes up to 20 gallons of cleaning solution
- Acid-free and safe for surrounding plants and grass
- Free-rinsing formula prevents streaking on brick
Good to know
- Some users found it less effective on deeply set oil without dwell time
- A few reports of no visible improvement on certain brick types
2. Zep Driveway, Masonry and Concrete Cleaner & Degreaser
Zep’s construction-grade degreaser is built for professionals tackling oil, grease, and tire marks on concrete, brick, and asphalt. The concentrated formula is designed to be applied with a mop or pump sprayer, scrubbed, and rinsed — but its real strength shines when used as a pressure washer pretreatment for extensive driveway and patio areas.
Customer reviews confirm it removes greasy grill spills and 2-year-old road salt from sealed garage floors, though some users noted multiple passes were needed on heavily aged stains. The 10-minute recommended contact time makes it a fast-acting option for commercial and residential jobs alike.
Zep recommends pre-treating older stains before a full surface clean, which improves deep cleaning action. While a few users expected more dirt-lifting power, the majority consider it a reliable, professional-grade solution for grease-heavy masonry projects.
Why it’s great
- Construction-grade degreaser effective on oil and tire marks
- Fast 10-minute dwell time for quick cleaning
- Works well as pressure washer pretreatment
Good to know
- May require multiple passes on old, embedded stains
- Not ideal for light routine maintenance without dilution testing
3. Dynamite Degreaser by Southeast Softwash
Dynamite Degreaser ships as Haz-Mat-rated cargo for a reason — this is the most aggressive formula in the lineup, designed to demolish oil, grease, carbon, and tire stains that standard cleaners cannot touch. It targets high-traffic commercial surfaces like dumpster pads, gas stations, and drive-throughs, but works equally well on residential concrete driveways.
Professional users report that it cuts through 46 years of built-up grease with no scrubbing — just spray, let it sit for ten seconds, and hose off. The ability to downstream the degreaser through a pressure washer makes it efficient for covering large commercial lots without manual dilution.
Opinions are split: some professionals call it their go-to degreaser for over three years, while a few found it ineffective on simple grease stains compared to cheaper alternatives. Given its extreme strength, it is best reserved for the toughest masonry staining jobs where lighter formulas fail.
Why it’s great
- Haz-Mat strength destroys heavy oil and carbon stains
- Can be downstreamed through pressure washer for large areas
- Minimal scrubbing required; quick ten-second dwell time works
Good to know
- Too strong for routine light cleaning; overkill for moss or dirt
- Some users report inconsistent results on certain grease types
4. Karcher Stone Cleaner 5 L Canister
Karcher’s stone cleaner is a ready-to-use liquid formulated specifically for Karcher pressure washers, designed to dispense directly from the machine’s detergent tank. It works on all stone surfaces including brick, concrete, and natural stone, and provides a lemon-scented clean without the need for measuring concentrates.
Customer feedback is overwhelmingly positive, with many praising its gentle yet effective cleaning on cars, stone patios, and brick walls. The 5-liter canister offers a convenient, long-lasting supply for Karcher owners who want a hassle-free drop-in solution without mixing.
It is worth noting that this product appears to double as an excellent car shampoo, as reviewers frequently mention the brilliant shine it leaves on vehicles. For brick and stone cleaning, it is effective on light dirt and grime, but may lack the heavy stain-lifting power of concentrated degreasers.
Why it’s great
- Designed for direct use with Karcher pressure washers
- Large 5-liter canister for extended use
- Pleasant lemon scent and gentle on surfaces
Good to know
- Not a concentrate; lower cleaning power for heavy stains
- Primarily suited for Karcher brand equipment
5. Serveon Sealants Concrete Cleaner (Concentrated Formula)
Serveon Sealants delivers a water-based, VOC-compliant concentrate that excels at removing rust deposits, lime, hard water, efflorescence, and algae from concrete and stone. Its strength lies in its flexibility — users report great results diluting 10:1 for light stains and 1:1 for deep oil removal on driveways.
Real-world reviews highlight that a 1:1 mix with a 20-minute dwell time removed roughly 90% of years-old oil stains from concrete, with no scrubbing needed. The formula also works as a surface etch preparation for sealers, making it a two-in-one cleaner and prep solution for those planning to reseal after washing.
While it performed best on light-to-moderate stains, some users noted it struggled with long-standing driveway discoloration even at full strength. The bottle’s built-in level gauge is a thoughtful addition for accurate mixing.
Why it’s great
- Versatile dilution range from 10:1 to full strength
- Non-irritating to skin with no strong fragrance
- Prepares surface for sealer bonding when used undiluted
Good to know
- Less effective on deeply aged driveway stains even at 1:1
- Relatively small coverage area of 100–200 sq ft per gallon
6. Quality Chemical Paver Magic
Paver Magic from Quality Chemical is a high-power cleaner engineered specifically for concrete, brick, and paver surfaces, covering up to 500 square feet per gallon when mixed. Professional pressure washers report using it at a 50/50 mix as a pre-spray on driveways and pavers to remove heavy moss without needing bleach.
Some users had catastrophic results — a paver patio lost all color and turned white after drying, leading to legal action. The formula behaves similarly to bleach and can whiten surfaces unevenly if not applied uniformly across the entire area.
It is best suited for full-area treatments where color matching across the entire surface is acceptable. For selective spot cleaning or color-sensitive stone, it poses a risk of permanent whitening. Use with caution on colored or sealed pavers.
Why it’s great
- High coverage of up to 500 sq ft per gallon
- Effective at removing moss and heavy organic growth
- Professional pressure washers report good results with 50/50 mix
Good to know
- Can permanently whiten or discolor colored pavers and brick
- Not suitable for oil or grease stain removal
- White residue can be difficult to remove if not rinsed thoroughly
7. Southeast Softwash Southern Drawl
Southern Drawl is not a standalone brick cleaner but a surfactant designed to be mixed with bleach or sodium percarbonate for soft washing applications. Its wetting agents increase “cling time,” keeping the bleach mixture on vertical brick and siding long enough to kill mold, moss, and mildew without constant reapplication.
Users love the clean citrus scent and the thick suds that signal active coverage. Typical mixing is 2–4 ounces per gallon of bleach, and the formula rinses clean from windows, vinyl siding, and gutters without residue. It is ideal for pressure washer downstream injectors and soft wash systems.
For brick specifically, Southern Drawl works best as part of a two-step process: apply the bleach-surfactant mix for organic stain removal, then follow with a dedicated brick degreaser for oil and carbon stains. It will not remove oil or tire marks on its own but is essential for biological growth on shaded brick.
Why it’s great
- Excellent cling time for vertical brick and siding
- Pleasant citrus scent masks bleach odor
- Rinses clean without residue on windows and gutters
Good to know
- Requires mixing with bleach; not a standalone cleaner
- Does not remove oil, grease, or tire marks from brick
- Shipping to remote areas can be expensive
