Simple Green Oxy Solve Concrete Cleaner -- Best All-Purpose Paver Cleaner
Simple Green Oxy Solve uses oxygenated bleach rather than chlorine to clean and brighten concrete pavers without the plant-killing, color-stripping risks of standard bleach. It works on oil, food stains, mold, mildew, and general environmental grime. Dilute with water at the recommended ratio, apply with a pump sprayer, scrub with a stiff brush, and rinse. On severely dirty pavers a pressure washer rinse speeds the job. It is safe for most paver types including pigmented concrete and natural stone, and it is biodegradable once rinsed. For a single cleaner that handles most routine paver maintenance in one purchase, this is the reliable starting point.
Check price on Amazon →Dirty pavers drag down the look of any outdoor space. Our picks for the best concrete paver cleaner tackle oil, efflorescence, algae, and ground-in grime without damaging the surface or jointing sand.
Concrete pavers collect grime fast. Oil drips from parked cars, efflorescence migrates to the surface as salts from below, algae and moss claim shaded spots, and general environmental dirt dulls the color year by year. Regular cleaning keeps pavers looking fresh, prevents stains from setting permanently, and extends the life of the jointing sand that holds the surface together. The best concrete paver cleaner matches the stain type: a general purpose degreaser for grease, a specialized efflorescence remover for white haze, and a biological treatment for green algae growth.

Simple Green Oxy Solve Concrete Cleaner -- Best All-Purpose Paver Cleaner
Simple Green Oxy Solve uses oxygenated bleach rather than chlorine to clean and brighten concrete pavers without the plant-killing, color-stripping risks of standard bleach. It works on oil, food stains, mold, mildew, and general environmental grime. Dilute with water at the recommended ratio, apply with a pump sprayer, scrub with a stiff brush, and rinse. On severely dirty pavers a pressure washer rinse speeds the job. It is safe for most paver types including pigmented concrete and natural stone, and it is biodegradable once rinsed. For a single cleaner that handles most routine paver maintenance in one purchase, this is the reliable starting point.
Techniseal Paver and Masonry Cleaner -- Best for Professional-Quality Results
Techniseal is the brand most professional hardscape installers use when prepping new pavers before sealing and maintaining installed paver surfaces. It is a pH-balanced acid-based formula that removes efflorescence, mortar haze, and surface calcium deposits without etching the concrete or disturbing joint sand. On natural clay or manufactured concrete pavers alike, it restores the original color with noticeably less scrubbing than general cleaners. Dilute with water for routine maintenance or use at a stronger dilution for initial installation cleanup. It requires rinsing thoroughly and is not recommended for aluminum, zinc, or polished marble surfaces.
Zep Concrete Cleaner and Degreaser -- Best for Oil and Grease
Driveways and parking areas with concrete pavers collect petroleum stains that standard multipurpose cleaners cannot break down effectively. Zep's concentrated alkaline degreaser is formulated to emulsify oil, grease, and automotive fluid stains on porous concrete surfaces. Apply it to the dry stain, let it penetrate for 3 to 5 minutes to work on the stain, then scrub with a stiff brush and rinse with a hose or pressure washer. For fresh oil stains it often removes the stain completely. For old, set stains, repeat applications progressively lighten the discoloration. It is also effective on tire marks and general traffic grime.
CLR PRO Calcium Lime and Rust Remover -- Best for Efflorescence
Efflorescence is the white haze that forms when water carries calcium salts to the paver surface and they dry as deposits. It is one of the most common paver complaints and one of the most stubbornly resistant to general cleaning products. CLR PRO targets the calcium and lime compounds specifically. Apply, let it dwell for 2 minutes, scrub, and rinse. On light efflorescence one application resolves the problem. Heavy buildup may require two applications. It also removes rust staining from metal furniture legs sitting on pavers -- one of the other common surface discolorations that general cleaners miss entirely.
Wet and Forget Outdoor Moss Mold Killer -- Best for Biological Growth
Shaded pavers in humid climates develop green and black biological growth -- algae, moss, and mold -- that standard cleaners remove temporarily but which regrow within weeks. Wet and Forget takes a different approach: apply it and walk away. It works slowly over weeks as rain activates the biocide, killing biological growth at the root level so regrowth is delayed significantly. No scrubbing required, which makes it ideal for large paver areas like long walkways and wide patios where scrubbing every square foot is not practical. Reapply once a year in high-growth environments to maintain results.
How to choose
What to consider
Match the cleaner to the primary stain type. General grime and mold calls for an all-purpose oxygenated cleaner. Oil and grease needs an alkaline degreaser. Efflorescence and mineral deposits require an acid-based efflorescence remover. Biological growth like algae and moss responds best to dedicated biocide treatments. For new pavers before sealing, use a professional masonry cleaner to remove construction residue. Always test any cleaner on a small, inconspicuous area first, especially on colored or pigmented pavers, to confirm it does not affect the finish. Follow cleaning with a quality sealer to slow re-soiling and simplify future maintenance.
What to consider
After cleaning, seal your pavers for long-term protection with the [best concrete patio sealer](/articles/best-concrete-patio-sealer) to resist future staining and biological growth. For decorative upgrades alongside your clean pavers, explore the [best concrete patio stain](/articles/best-concrete-patio-stain) for color enhancement options.

Common questions
Diluted bleach can kill algae and mold on concrete pavers, but it can bleach out pigmented pavers, damage nearby plants and lawn, and leave residue that degrades joint sand over time. Purpose-made paver cleaners with quaternary ammonium or oxygenated bleach formulas clean as effectively as chlorine bleach without those side effects. Reserve bleach for severe mold infestations only.
High-pressure washing above 2,000 PSI aimed directly at joints can displace polymeric sand and regular jointing sand. Use a 25-degree nozzle at moderate pressure rather than a zero-degree jet, and aim at the paver surface rather than the joints. After any aggressive washing, inspect joints and replace displaced sand, then apply a paver sealer to stabilize it.
