Black algae seams, green moss creeping between joints, and white efflorescence dusting the surface — brick pavers demand a cleaner that actually penetrates porous clay without leaving a hazy residue. The wrong formula leaves bare spots, requires hours of scrubbing, or dulls the paver’s natural color.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years analyzing chemical formulations, comparing coverage rates, and studying owner feedback to determine which outdoor cleaners effectively break down biological stains on paver surfaces without damaging the surrounding landscape.
Whether you are restoring a patio, cleaning a walkway, or prepping a driveway for resealing, choosing the right product determines whether the job takes one afternoon or an entire season. This guide breaks down the top formulas to help you find the best brick paver cleaner for your specific stain type and application method.
How To Choose The Best Brick Paver Cleaner
Not all outdoor cleaners treat brick pavers the same. The porous nature of clay and concrete pavers means the cleaning agent must penetrate below the surface, while the formula must also be safe for surrounding plants, grass, and the paver seals. Here is what matters most when selecting a product.
Concentrate vs Ready to Use
Concentrates require dilution with water before application but treat far more square footage per bottle — often 4 to 6 times more than a ready-to-use formula. If you are cleaning a large patio or driveway, a concentrate delivers better value. Ready-to-use sprayers are more convenient for small areas, spot cleaning, or quick touch-ups on a few pavers.
Active Ingredient: Bleach vs Peroxide vs Acid
Sodium hypochlorite (bleach) cleaners work fast on black mold and mildew but can damage nearby plants, bleach clothing, and produce strong fumes. Peroxide-based formulas like those from Simple Green are safer around kids and pets, though they may require a second pass on heavy stains. Industrial-strength vinegar (45% acetic acid) is effective on mineral deposits and efflorescence but requires careful handling — the vapor alone can irritate eyes and throat. Bleach-free formulas are usually the safer choice for brick pavers surrounded by lawn or flower beds.
Application Method: Spray, Mop, or Pressure Washer
Products labeled “no scrub” rely on rain and wind to lift stains over several days or weeks. If you want immediate results, a cleaner designed for use with a pressure washer — like Simple Green Oxy Solve — delivers visible change within minutes. Manual application with a pump sprayer or mop works well for both concentrates and ready-to-use formulas but requires you to control runoff so it does not pool near plant roots.

In‑Depth Reviews
1. Simple Green Oxy Solve Total Outdoor Cleaner
Simple Green Oxy Solve cleaner stands out for its massive coverage — a single gallon concentrate dilutes to cover up to 6,400 square feet. That is roughly 10 times the coverage of typical ready-to-use formulas, making it the most economical option for cleaning an entire driveway, patio, or brick walkway. The peroxide-based formula lifts dirt, moss, and mildew without bleach, and it is EPA Safer Choice certified, meaning it is safer around children, pets, and nearby plants.
The cleaner works best when applied with a pressure washer — the foam clings to vertical paver surfaces, penetrates pores, and rinses off without leaving a chalky residue. Owners report that tough stains on concrete and brick fade noticeably within minutes, and the continuing oxidation action often leaves pavers looking better a day or two after washing. For manual pump-sprayer use, the concentrate still works but may require a second pass on heavily shaded areas with long-established algae growth.
Unlike bleach-based alternatives, this formula has no harsh chemical odor, and it does not yellow nearby vegetation. The only practical downside is that very stubborn black stains sometimes need a second application after a few days, particularly on north-facing brick walls that stay damp year-round.
What works
- Exceptional coverage at 6,400 sq ft per bottle
- Bleach-free and safe for kids, pets, and plants
- Works well with pressure washers for fast results
What doesn’t
- Pump sprayer application requires more passes for heavy stains
- Less effective on deep black mold without a second application
2. Rust-Oleum Jomax Spray Once
Rust-Oleum Jomax is a bleach-free concentrate designed for users who want to spray and walk away. Each bottle makes up to 5 gallons of cleaning solution, covering roughly 1,500 square feet. The formula relies on natural weather conditions — rain and wind — to slowly lift mold, mildew, and algae over 1 to 2 days rather than doing the work instantly. This makes it ideal for homeowners who cannot dedicate an entire weekend to scrubbing and prefer a set-and-forget approach.
Owner feedback consistently highlights its effectiveness on siding, fences, decks, and brick. One user noted that green stains faded completely within 48 hours, while black stains turned gray but did not vanish entirely after a single treatment. The product is applied with a standard pump-up garden sprayer, and no rinsing or scrubbing is required — just wet the surface and wait. A slight chemical smell dissipates within an hour after application.
For brick pavers specifically, Jomax works well on light to moderate algae and moss but struggles with lichen and long-established black stains. Several owners reported that after a few years of seasonal use the product prevents regrowth better than any other formula they tried. The main catch is that the concentrate is thick — it splashes easily during mixing, and the instruction to dilute 1:4 with water means you need to plan ahead with a 1-gallon or 2-gallon sprayer.
What works
- True no-scrub, no-rinse application saves labor
- Bleach-free and safe for surrounding landscape
- One bottle makes 5 gallons of solution
What doesn’t
- Slow-acting — results take 1 to 2 days
- Less effective on thick black mold and lichen
3. Natural Armor 45% Industrial Strength Vinegar
Natural Armor 45% Vinegar is not a traditional paver cleaner — it is an industrial-strength acetic acid solution that kills weeds, dissolves mineral deposits, and strips efflorescence from brick and concrete surfaces. At 9 times stronger than household vinegar, it acts fast on the white powdery residue (efflorescence) that often appears on new brick pavers, and it eliminates moss and algae within 24 hours of direct contact. The 128-ounce gallon provides long-term value for both weed control and paver restoration.
Owners report outstanding results on weeds growing between paver joints, with roots dying within a single day, including tall weeds up to 3 feet high. Unlike bleach-based cleaners, this formula is safe for pets once dry — though the vinegar smell is intense during application, requiring a downwind approach and eye protection. It also cleans window screens, grout, and rust from tools, making it a multi-surface tool for homeowners who want one bottle for multiple jobs.
On brick surfaces, the acid can slightly etch old or weathered pavers if left to pool for extended periods. The formula is best applied with a pump sprayer on a still, dry day and left to work without rinsing. For heavy biological stains like black mold, the acid may need a second pass, and it is not designed for pressure washer application — it should be used as a direct spray treatment.
What works
- Kills weeds and dissolves efflorescence fast
- Safe for pets and kids once dry
- Multi-surface — pavers, grout, tools, windows
What doesn’t
- Strong vinegar smell requires ventilation and goggles
- Can etch old pavers if allowed to pool
4. Clorox Outdoor Concentrate Solution
Clorox Outdoor Concentrate is a bleach-based super-concentrate that tackles the toughest black mold and mildew on brick, siding, and metal surfaces. At 120 ounces, it is the largest volume among the products tested, and the concentrated formula means a little goes a long way — owners report a bottle lasting for multiple treatments over several years when stored properly. The bleach actively kills spores on contact, turning green and black stains white within minutes of application.
Owner feedback is overwhelmingly positive for heavy-duty jobs: black mold on painted walls vanished without scraping after full-strength application, and siding stayed free of green growth for 2 to 3 years after a single treatment. For brick pavers, the best results come from diluting the concentrate and applying with a sprayer or brush, followed by a rinse with a garden hose. The formula also whitens concrete and removes rust-colored stains from metal fixtures.
The major drawback is the bleach itself — it produces strong fumes that require a respirator and safety glasses, and it will bleach clothing immediately on contact. Surrounding plants must be flushed with water before and after application to prevent leaf burn, and the product loses potency if not used within a few months of opening. It is not a set-and-forget solution; it requires active application and proper runoff management.
What works
- Fast-acting — mold vanishes in minutes
- High concentrate covers numerous applications
- Prevents regrowth for 2 to 3 years
What doesn’t
- Strong fumes require respirator and ventilation
- Bleaches clothing and can damage plants nearby
5. Wet & Forget Outdoor Multi-Surface Cleaner
Wet & Forget is the most straightforward product in this lineup — unscrew the cap, spray directly onto dry brick pavers on a cool day, and let rain and wind do the work over the following weeks. The ready-to-use formula (no mixing, no dilution) treats 60 to 180 square feet per 64-ounce bottle, making it best suited for small patios, entryways, or spot treatments rather than whole driveways. It is bleach-free and non-acidic, so it will not harm nearby grass or flower beds.
Owner reviews reveal a consistent pattern: green algae stains fade within 1 to 2 weeks, black mildew takes 1 to 2 months, and long-established black stains can persist for 6 to 12 months before disappearing completely. The formula is ideal for north-facing brick walls, covered porches, and shaded paver areas where moisture accumulates but direct sunlight is limited. It also works well on screen enclosures, headstones, and outdoor upholstery — far beyond just brick.
The slow action is the trade-off. If you need a clean patio for a weekend barbecue, this is not the product to use — you need to apply it and wait weeks for full results. Some owners noted that using a mop on a pole rather than the sprayer reduced wasted product and improved coverage on vertical surfaces. The product also has little effect on lichen, and black stains may only turn gray after the first season.
What works
- Zero scrubbing or rinsing — truly forget it
- Safe for plants, pets, and screens
- Works on multiple outdoor surfaces
What doesn’t
- Very slow — results take weeks to months
- Limited coverage per bottle
- Ineffective on lichen and heavy black stains
Hardware & Specs Guide
Concentrate vs Ready-to-Use Coverage
Concentrates like Simple Green Oxy Solve and Rust-Oleum Jomax require dilution with water, typically 1 part cleaner to 4 parts water, yielding far more usable solution per bottle. A 1-gallon concentrate can treat 4 to 6 times more square footage than a 64-ounce ready-to-use sprayer. If your paver area exceeds 300 square feet, a concentrate will save you money and reduce the number of bottles you need to store.
Active Ingredient Safety Profile
Bleach (sodium hypochlorite) cleaners offer the fastest kill on mold and mildew but require you to flush nearby plants, wear a respirator, and avoid contact with clothing. Peroxide-based cleaners are slower but pose almost no risk to vegetation. Industrial-strength vinegar (acid) is excellent for mineral deposits and weeds but can etch unsealed pavers. Choose the active ingredient based on whether you prioritize speed or safety around your landscape.
