Which concrete cleaner works best with a pressure washer?

Simple Green Oxy Solve Total Outdoor Cleaner is the most versatile pick because it covers concrete alongside wood, vinyl, brick and composite. For a driveway-only job, Simple Green Oxy Solve Concrete and Driveway gives a more focused stain list.

The product that fits best depends on your driveway. Oil and tire marks point toward a stain-focused cleaner, while a driveway connected to brick paths or a stone patio may call for broader surface compatibility.

If you are still deciding which detergent belongs in the machine, our guide to What Soap Can I Use in a Pressure Washer? covers detergent use and pressure washer compatibility. The application method matters too: see what a soap nozzle does on a pressure washer.

Best concrete cleaners for pressure washers

The top concrete cleaner for pressure washer use depends on the surface, stains and application setup. These picks are ordered by score, with a distinct use case for each one.

1

Simple Green Oxy Solve Total Outdoor Cleaner: Best for mixed outdoor surfaces

9.7/10Our score

• Peroxide cleaner
• For concrete, wood, vinyl, brick and composite
• Pressure washer and manual use
• Covers up to 6,400 sq ft

A flexible pick for driveways and other outdoor surfaces around the home. Simple Green says one bottle covers up to 6,400 sq ft.

See it on Amazon

Pros

• Works across several outdoor surface types
• Peroxide-powered formula
• Manual or pressure washer use

Cons

• Not limited to concrete-specific jobs

Simple Green Oxy Solve Total Outdoor Cleaner is the broadest pick here for a home with more than one outdoor surface to clean. Simple Green describes it as a peroxide-powered concentrate for pressure washer and manual use on wood, vinyl, concrete, brick and composite.

The broad surface range is useful when a concrete driveway meets a vinyl-sided home or a brick walkway. Simple Green says one bottle can cover up to 6,400 sq ft, though the actual area depends on dilution and soil.

This isn't the most concrete-specific option in the group, so consider the driveway formula below if oil, rust or tire marks are your main concern. For mixed jobs, though, one outdoor cleaner can simplify your supplies.

Best for a driveway plus other outdoor surfaces, such as a patio, fence or siding. Keep the washer's detergent instructions close and apply only to compatible surfaces.

2

Simple Green Oxy Solve Concrete and Driveway: Best for common driveway stains

9.6/10Our score

• Made for driveways, walkways, patios and masonry
• Targets oil, rust, grease and tire marks
• Peroxide-powered formula
• Pressure washer directions included

This concrete-focused option targets oil, rust, grease, automotive fluids, tire marks and exhaust buildup. Pressure washer directions call for a 3–5 minute dwell before rinsing.

See it on Amazon

Pros

• Concrete and driveway focus
• Targets several vehicle-related stains
• Includes pressure washer steps

Cons

• Keep the cleaner damp during its dwell time

Simple Green Oxy Solve Concrete and Driveway is the focused choice for a concrete driveway with common vehicle-related marks. Its stated targets include oil, rust, grease, automotive fluids, tire marks and exhaust buildup.

The pressure washer directions call for wetting the surface with plain water at low pressure, applying the cleaner at low pressure, waiting 3–5 minutes, then rinsing at high pressure. Keep the section wet during that wait, and follow the washer manual for its detergent feed.

For manual use, the directions say to mix 1 part cleaner with 20 parts water, wet the surface, scrub with a soft-bristle brush or sponge, and rinse. That gives you an option for a smaller stain without setting up the pressure washer.

Best for common driveway stains, especially where oil and tire marks are visible. Compare it with the broad Oxy Solve if you also plan to wash siding or wood.

3

Krud Kutter Multi-Purpose Pressure Washer Concentrate: Best for large mixed-surface jobs

9.4/10Our score

• For concrete, brick, stone, wood and more
• Targets dirt, oil and grease
• One gallon makes up to 20 gallons of solution
• Covers up to 5,800 sq ft

A broad surface range and large stated coverage suit a driveway plus other exterior cleaning. Krud Kutter says to allow 3–5 minutes for the cleaner to penetrate before rinsing.

See it on Amazon

Pros

• For concrete and many other surfaces
• Targets oil, grease and tough dirt
• Bleach-free formula

Cons

• Product description gives a different solution yield than the bullet details

Krud Kutter Multi-Purpose Pressure Washer Concentrate suits a large exterior job that includes concrete and other materials. Its named surfaces include concrete, brick, stone, wood, vinyl and aluminum siding, and it targets dirt, oil, grease, bird droppings and tree sap.

Krud Kutter says a gallon makes up to 20 gallons of solution and covers up to 5,800 sq ft. Its directions call for 3–5 minutes of dwell time before rinsing; avoid letting the cleaner dry on the surface.

There is a difference between the product's bullet details and description about how many gallons of solution one gallon makes. Use the container directions to confirm the right dilution for your washer and cleaning task.

Best for large mixed-surface jobs where a driveway is only part of the work. The bleach-free formula and broad surface list make it a flexible option for exterior maintenance.

4

KÄRCHER Concrete & Driveway Cleaner for Pressure: Best for concentrated driveway cleaning

9.2/10Our score

• For concrete, brick, masonry and stone
• Makes up to 40 gallons
• For pressure washer, foam cannon or manual use
• Quick-rinsing formula

The concentrate is designed for concrete, brick, masonry and stone. Its application options suit buyers choosing between a pressure washer, foam cannon or manual cleaning.

See it on Amazon

Pros

• Concrete and masonry focus
• High stated solution yield
• Several application methods

Cons

• Avoid letting it dry during its dwell time

KÄRCHER Concrete & Driveway Cleaner is a concentrated detergent for concrete, brick, masonry and stone. Kärcher says it makes up to 40 gallons of ready-to-use cleaner and can be applied with a pressure washer, foam cannon or by hand.

That yield makes it a practical candidate for repeated hard-surface cleaning, especially if you also have masonry or stone paths. The directions describe applying it through the washer's detergent tank or siphon tube, allowing it to penetrate for 1–5 minutes, and rinsing at high pressure.

Keep the surface wet while the detergent sits. For stubborn dirt, Kärcher says a soft-bristle brush can help before you rinse.

Best for concentrated driveway cleaning when you want multiple ways to apply the detergent. Check your washer manual for the correct tank or siphon setup.

5

Zep Cleaner Concrete DRVWY 128OZ ZUCON128: Best for a basic driveway cleaner

8.9/10Our score

• Concrete and driveway cleaner
• Zep focuses on home, business and automotive cleaning

This is a straightforward Zep concrete and driveway option. The available details give little application guidance, so confirm pressure washer compatibility and use directions before choosing it.

See it on Amazon

Pros

• Concrete and driveway focus
• Simple product choice

Cons

• Application details are limited

Zep Cleaner Concrete DRVWY 128OZ ZUCON128 is a simple concrete and driveway cleaner from Zep. The available product details do not specify how it should be diluted or fed through a pressure washer.

That gap matters if you need a detergent for a particular washer setup. Confirm the container instructions and compatibility before you add it to a tank or injector.

Choose this option when you want a concrete and driveway cleaner and can verify that its directions match your machine. If you need clear pressure washer application guidance before buying, consider one of the other picks.

Best for a basic driveway cleaner when you can confirm the correct application directions. Don't assume every concrete cleaner is approved for every detergent system.

6

Zep Driveway and Concrete Pressure Wash Cleaner: Best for oil-stained hard surfaces

8.6/10Our score

• For concrete, brick, asphalt and aggregate
• Targets oil stains, dirt and grime
• For pressure washers with downstream injectors
• Contains sodium hydroxide

This construction-grade concentrate is aimed at oil, dirt and grime on hard surfaces. Zep warns that it can remove water-based paint and concrete sealers.

See it on Amazon

Pros

• Names several hard surfaces
• Explicit downstream injector compatibility
• Targets oil stains and grime

Cons

• Not for wood, painted, sealed or stained surfaces that will not be refinished

Zep Driveway and Concrete Pressure Wash Cleaner is a construction-grade concentrate for concrete, brick, asphalt and aggregate. Zep says it lifts oil, dirt and grime and is formulated for manual application and pressure washers with downstream chemical injectors.

Its formula contains sodium hydroxide and can remove water-based paint and concrete sealers. Zep says not to use it on wood or on painted, sealed or stained surfaces that will not be refinished.

Wet nearby plants, shrubs and grass before, during and after cleaning, as Zep advises. For chemical handling guidance, see bleach foamer guidance.

Keep the cleaner on the intended hard surface and avoid runoff onto areas you want to preserve.

Best for oil-stained hard surfaces when you have a compatible downstream injector and the surface can tolerate this formula. Check the surface restrictions before use.

7

Serveon Sealants Concrete & Limestone Cleaner: Best for limestone and mineral deposits

8.3/10Our score

• For concrete and limestone
• Targets oil, rust, hard water deposits and efflorescence
• Concentrated water-based formula
• Coverage estimate of 100–200 sq ft per gallon

This cleaner addresses mineral deposits, rust and oil on concrete and limestone. Serveon gives a coverage estimate of 100–200 sq ft per gallon and cautions that the formula can etch surfaces.

See it on Amazon

Pros

• Targets mineral deposits and rust
• For concrete and limestone
• Water-based formula

Cons

• Coverage is lower than several broad exterior concentrates
• Can etch surfaces

Serveon Sealants Concrete & Limestone Cleaner is aimed at concrete and limestone with mineral deposits, rust, oil or grime. The formula is concentrated, water-based and designed for concrete and calcium-based surfaces.

Serveon gives an estimated coverage of 100–200 sq ft per gallon. Its directions describe dilution for general cleaning and stronger solutions for stubborn stains, but the formula can etch surfaces, so follow the container directions and take care with the substrate.

This is a more specialized pick than a broad driveway detergent. It may suit a concrete or limestone surface with efflorescence, hard water deposits or rust, where those stain targets matter more than wide coverage.

Best for limestone and mineral deposits on compatible surfaces. Confirm the pressure washer application method before using it through a machine.

How do you choose a concrete cleaner for a pressure washer?

Choose by stain, surface and washer connection first. Concentration and coverage help compare value, but they don't replace compatibility and safe application.

Which cleaner targets driveway oil and tire marks?

Simple Green Oxy Solve Concrete and Driveway names oil, grease, automotive fluids and tire marks. Zep Driveway and Concrete Pressure Wash Cleaner also targets oil and grime, but it contains sodium hydroxide and can strip water-based paint and concrete sealers.

For mineral stains such as rust, hard water deposits or efflorescence, Serveon Concrete & Limestone Cleaner lists those targets. Its directions warn that it can etch surfaces, so test an inconspicuous area if the container recommends it.

Does the surface include brick, stone or asphalt?

Read the surface list before applying detergent. Kärcher covers concrete, brick, masonry and stone, while Zep's pressure wash concentrate names concrete, brick, asphalt and aggregate.

A broad outdoor formula can be useful if the same job includes siding or a deck. For other exterior materials, compare best deck cleaners for pressure washers and best vinyl siding cleaners for pressure washers.

How will the detergent enter your pressure washer?

Pressure washers use different detergent methods, including onboard tanks, siphon tubes and downstream injectors. For a brand-specific walkthrough, see Greenworks washer soap guide.

The cleaner must support your machine's method, and the manual should guide the connection and pressure setting.

Zep explicitly names downstream injector use for its driveway concentrate. The Kärcher directions refer to an onboard detergent tank or siphon tube, while Simple Green Oxy Solve Concrete and Driveway describes use through a siphon tube or soap reservoir.

If you need to buy an injector separately, compare downstream injectors for a pressure washer. A cordless pressure washer may have a different detergent setup, so check its manual before assuming a standard injector will work.

How much cleaner will the job need?

Use coverage and dilution claims as rough planning figures, not a promise for every driveway. Simple Green says its Total Outdoor Cleaner can cover up to 6,400 sq ft, while Krud Kutter says it covers up to 5,800 sq ft.

Kärcher says its concentrate makes up to 40 gallons, and Krud Kutter says up to 20 gallons in its bullet details. Soil level, surface texture and dilution affect how much ready-to-use solution a job needs.

How should you apply concrete cleaner before pressure washing?

Apply detergent at the pressure and dwell time specified for that cleaner, then rinse thoroughly before it dries. Clean one manageable section at a time so the product stays wet for its full contact period.

Remove loose debris first, protect nearby plants as directed, and wet the concrete if the cleaner's directions call for it. Avoid spraying detergent onto glass, painted surfaces, or sealed areas unless the product permits that use.

The spray tip and distance affect how the water hits the concrete, so choose them with care. Our guide to which nozzle to use for concrete explains how to match the nozzle to the surface and task.

For a washer detergent connection, use the correct low-pressure soap method. Don't feed a cleaner through the high-pressure side unless the manufacturer and washer manual allow that setup.

Can you use bleach instead of concrete cleaner?

A concrete detergent is usually the clearer choice when its directions match your surface and stain. Bleach compatibility depends on the washer design and the product's instructions, so don't pour household bleach into a pressure washer without checking first.

Bleach can affect plants, nearby materials and washer components. Read Can You Use Bleach in a Pressure Washer? before choosing it as a substitute for a concrete cleaner.

Which concrete cleaner should you choose?

Choose Simple Green Oxy Solve Total Outdoor Cleaner if you need one concentrate for concrete and several other outdoor surfaces. Pick Simple Green Oxy Solve Concrete and Driveway for a driveway with oil, tire marks or rust, or Kärcher when its up-to-40-gallon yield and application options suit your setup.

For a downstream injector and hard surfaces such as concrete, brick or asphalt, consider Zep Driveway and Concrete Pressure Wash Cleaner after checking its sodium hydroxide warning and surface restrictions. For limestone or mineral deposits, Serveon is the specialized option, but account for its etching caution and lower stated coverage.

Frequently asked questions

What cleaner should I use on a concrete driveway?

Choose a cleaner labeled for concrete and the stain you need to remove. Simple Green Oxy Solve Concrete and Driveway names oil, rust, grease, automotive fluids and tire marks, while Kärcher is made for concrete, brick, masonry and stone.

Check surface restrictions and application instructions before you start.

Can I put concrete cleaner in a pressure washer?

Only use a cleaner that allows pressure washer application, and follow the washer manual for its detergent tank or siphon tube. Some cleaners are designed for downstream injectors, which use a different setup.

Apply detergent at low pressure when the cleaner's directions call for it, then rinse as directed.

How long should concrete cleaner sit before rinsing?

Follow the cleaner's own directions and keep it from drying on the concrete. Simple Green Oxy Solve Concrete and Driveway calls for 3–5 minutes before a high-pressure rinse, and Krud Kutter also gives a 3–5 minute dwell.

Work in manageable sections so you can rinse each one on time.

Can concrete cleaner damage plants or sealers?

It can, depending on the formula and nearby surfaces. Zep Driveway and Concrete Pressure Wash Cleaner contains sodium hydroxide and can remove water-based paint and concrete sealers.

Zep also advises wetting nearby plants, shrubs and grass before, during and after cleaning.

Read the product directions for your chosen cleaner.

Do I need a soap nozzle to apply driveway cleaner?

Use the low-pressure detergent method your washer supports, such as its onboard tank, siphon tube or a compatible downstream injector. A soap nozzle may be part of that setup, but nozzle choice depends on your washer and cleaning plan.

Check the manual before connecting detergent.
