Your bluestone turns dull and gray because dirt, algae and mineral film settle into its open surface. An acid-based cleaner can etch that haze permanently into the stone. The five options below split into two jobs. A gentle pH-neutral wash (a cleaner with a neutral pH that won’t etch stone) keeps stone looking finished. A peroxide or bleach-based outdoor wash (a stronger cleaner that kills algae and lifts black stains) handles a paver patio that has gone green and black. Choose the job — neutral wash or algae-killing outdoor wash — before you pick the bottle.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Bluestone is a dense, low-absorption stone, but it still hates acid and sits in the weather all year, so the cleaner you choose has to match both the stone and the grime. Here is how each of these five handles real bluestone paver cleanup, from a quick countertop wipe to a whole patio rinse-down and what each means for your best bluestone paver cleaner decision.
Top Picks
How To Choose The Best Bluestone Paver Cleaner
Start with what is actually on the stone. A patio that has gone green and black under the shade of a tree needs a different product than a bluestone hearth you wipe down after a spill. The wrong formula means a wasted weekend of scrubbing; the right one usually takes a single pass.
Match the formula to the stone, not just the stain
Bluestone is a natural stone with a slightly open surface, and strong acids can eat into it and leave a dull, etched patch that no cleaner will bring back. A pH-neutral cleaner is the safe starting point for anything you plan to seal or keep polished. Reserve harsher formulas for outdoor, unsealed surfaces where you can test a small corner first.
Read the yield, not the bottle size
A concentrate that dilutes into many gallons goes further than the label suggests. One gallon of a diluted concentrate can cover a whole paver patio, while a ready-to-use spray covers a countertop. Compare square feet of coverage per bottle, not just the jug size, when you are buying for a driveway-width job.
Decide if you want cleaning only, or cleaning plus protection
Some cleaners carry a small amount of sealer so the surface keeps its water resistance after the wash. That is helpful on interior counters and honed stone. If your bluestone pavers are already sealed, go plain and pH-neutral so you do not build up a hazy film.

Detailed Reviews
1. STONETECH RTU Revitalizer Fresh Citrus 1 Gallon
Our pick — 4.5+★ from 800+ verified ratings; the strongest balance of quality and price.
The gallon jug that cleans and reseals in one wipe, with no rinse step.
If your bluestone is finished, honed or set indoors as a counter or hearth, this is the safest place to start. It is a ready-to-use water-based liquid, meaning you do not mix anything — you spray, wipe, and walk away. The formula carries a built-in sealer and a mold and mildew resistant protection layer, so each wipe leaves a little more defense behind. It comes in a 1-gallon size, which is generous for interior touch-ups.
The brand lists the stone types it is built for, and that list is exactly what you want if your bluestone sits at the edge of natural stone work: marble, granite, limestone, travertine, slate, sandstone, flagstone and quartzite. Bluestone falls squarely into that natural-stone family. What wins owners over is the finish: it cleans and shines in one application without streaking on dark polished stone. The fresh citrus scent is mild by design, since it is tagged as a low-odor formula.
The honest catch is cost per job. One owner loves that it seals but says, “Just wish it were cheaper.” Also know this is a wipe-on interior cleaner, not a patio-washing powerhouse. A green, algae-covered paver patio in full weather needs the outdoor concentrates further down this list. The stated volume is 154 Fl Oz in a single pack, so the jug lasts a good while on normal indoor use.
Where it shines
- Cleans and reseals in one step, so dark stone keeps its sheen instead of drying dull.
- Water-based and biodegradable, with a low-odor fresh citrus scent instead of a chemical smell.
- Built-in sealer plus mold and mildew resistant protection extends the finish between deep cleans.
What to weigh first
- Priced higher per job than a basic cleaner, and the label carries no square-foot yield of its own.
- Built for interior counters and tile — a heavily algae-soiled paver patio needs an outdoor concentrate.
Made for: interior bluestone counters, hearths and tiled floors where you want a clean-and-shine wipe without a rinse.
Look past it for: a full outdoor paver patio that needs a pressure-washer or bleach-strength job.
2. StonePro Crystal Clean Ready-To-Use Spray 16 oz
A pH-neutral spray that guards sensitive stone and evaporates without a rinse.
The pH-neutral claim is the whole point here. On bluestone you keep polished or sealed, a neutral formula will not etch the surface the way an acid cleaner can, so you can use it with confidence instead of testing every corner. It is a rinse-less spray — you mist, you buff with a microfiber, and it evaporates without leaving residue or dullness behind. Handy size, too: it weighs 1.26 pounds in a slender 3 x 3 x 11-inch bottle, easy to grab and tuck under a sink.
The second job is sealing. Crystal Clean reinforces the protection of StonePro’s own sealers — Porous Pro, Ultimate Pro, Pro Sealer and Aqua Pro — and helps guard against water- and oil-borne stains that can quickly spoil a floor or countertop. Owners who had their surfaces redone often get steered to it. The recurring benefit is a finish that “looks great on counter tops, they shine.” It is made in the USA, and the maker says the company has led the industry for 25 years.
Where it is less useful: heavily textured stone. The formula is described as weak on unfilled, textured and pitted tiles, and on polished marble it can leave a haze if you over-apply — buff with a microfiber and you are fine. For a natural cleft bluestone paver, expect to spend more effort than on a honed face. Note that the bottle is a 16 oz ready-to-use spray, so it suits touch-ups, not a driveway.
Best for sensitive stone: if your bluestone is polished, sealed or paired with marble and stainless appliances, a neutral formula protects the investment while it cleans.
The texture limit: this is a smooth-surface specialist — the brand notes it underperforms on unfilled, textured and pitted tiles, so treat a rough paver as a different job.
Reach for this if: you want one safe daily spray that cleans and protects polished stone in a single buffed pass.
Skip the spray for: a large, rough or weathered paver area — a concentrate will go much further.
3. Simple Green Oxy Solve Total Outdoor Cleaner Concentrate
A peroxide-powered concentrate that softens outdoor grime so the pressure washer wins faster.
For an outdoor bluestone patio that has picked up mold, mildew and general dirt, a peroxide formula is the middle road — gentler than bleach, stronger than plain water. This is a concentrate you dilute for a pressure washer or for manual brushing, and the bottle lists coverage up to 6,400 sq. ft. That is a driveway-and-patio scale of job from one jug. It is heavy at 9.27 pounds, versus the 1.26 pounds of the StonePro spray, which tells you this is a pour-and-dilute product, not a handheld touch-up.
Safety around the yard is a clear theme. The formula is EPA Safer Choice Certified, a program that flags products with safer ingredients, which matters when kids and pets share the patio. Buyers report it is “safe for pets and plants (humans too).” The most-praised angle, though, is ease of use — it dilutes, foams well and rinses residue-free. It also cleans wood, vinyl, concrete, brick and composite, so a single jug handles the pavers and the furniture.
Set expectations honestly: cleaning performance is genuinely mixed. Some owners find it does a great job on mildew and patio furniture; others find it weaker than hoped on stubborn dirt, especially through a pump sprayer. In a timed comparison it cut cleaning time by half versus water alone, though it did not out-clean plain water. Use it with a pressure washer, let the foam dwell, and plan a second pass on tough stains. That is the fair read.
How to get the best from it: dilute, apply with the pressure washer, let the foam sit so the peroxide lifts the organic film, then rinse before it dries.
What it will not do: it speeds up a pressure wash more reliably than it replaces one — deep, set-in stains often need a second application.
A good fit for: homeowners who own a pressure washer and want a plant-safe, big-yield concentrate for patio and paver soiling.
Think twice if: you want a bottle that outperforms the washer on its own — this is a helper, not a replacement.
4. 30 SECONDS Pressure Washer Cleaner Concentrate
Bleach-strength concentrate built to erase black algae from hardscape in one dwell-and-rinse pass.
When bluestone has gone properly black with mold and algae, you want chlorine. This concentrate is powered by bleach to penetrate and dissolve discoloration, and it mixes into up to 20 gallons of solution from one bottle — a full-driveway quantity. The anti-corrosive formulation is designed for pressure washer tanks, so you are not risking the machine for the sake of a cleaner. Weight sits at 9.46 pounds, so you pour it carefully, not carry it around.
Coverage spans a long list: vinyl, metal, wood, composite, plastic, wicker, concrete, stone, brick and asphalt. For a bluestone paver patio, the process is apply, let it dwell and rinse — no scrubbing, which is the part people love. It dissolves lichen and green growth on hardscape; one owner reports a vinyl fence washed clean with a sponge, no pressure washer needed. The brand makes it in the USA from US and imported parts.
Two cautions before you buy. Bleach is bleach — this will fade clothing it touches, so dress for it. And residue is the real variable: some owners get siding that looks brand new, others report white streaky stains when the mix dries before rinsing. Keep the surface wet, rinse thoroughly and do not let it bake in the sun. Effectiveness and value both split down the middle in owner feedback, so test a hidden paver first.
What earns the slot: the raw stain-lifting strength of bleach, mixed 20 gallons at a time, with no scrubbing required on mold and algae.
The watch-out: it bleaches fabric and can leave residue if it dries on the surface — keep it wet and rinse it clean.
Best suited to: a badly algae-stained outdoor patio where bleach strength and a huge mixed yield are what you want.
Not for: interiors, sealed or polished stone, or anyone uneasy with a chlorine-based cleaner.
5. TIMBERTECH Composite DeckCleaner – 1 Gallon
A warranties-respecting concentrate that also handles paver cleanup, no harsh bite required.
This one is made specifically for TimberTech AZEK, PRO and EDGE capped decking (composite boards with a protective outer layer). The label guarantees it will not damage those products or compromise their warranties when used as directed. Crucially, the same line notes it “also can be used for DrySpace and Pavers.” So for a patio where bluestone sits beside composite decking or a railing, you can clean both with one jug and keep the warranty intact on the deck side. It is a biodegradable formula, and it works on stubborn spills and spot treatment as well as a full-surface wash.
The concentrate math is the selling point for bigger areas: properly diluted, one gallon yields 4 gallons of cleaner that cover approximately 1,000 square feet. That is a whole modest patio from one bottle. What owners keep coming back to is effectiveness, and the results show — the deck looks like new, and starting algae is gone. It attacks the algae at the source rather than just the surface film; a long-time TimberTech owner reports it keeps the deck looking good all year, where a hardware-store cleaner only lasted months.
Adjust your method and your expectations. This is a scrub-into-the-grooves cleaner, not a spray-and-rinse — plan on a brush for textured or grooved surfaces. It also tends to clean well without lifting white oxidation, so if your composite has gone chalky, look for a dedicated brightener instead. It weighs 2.82 ounces, easy to store. Value divides opinion — worth it to some, pricey to others — so buy to the yield.
Why it earns a spot
- One jug cleans composite decking and pavers, and the formula is warranted not to damage TimberTech surfaces.
- Dilutes to 4 gallons covering about 1,000 square feet, so a patio job stretches far per bottle.
- Biodegradable and effective — it removes the algae at the source and keeps surfaces looking good longer.
The trade-offs
- Requires scrubbing into grooves and textured surfaces, not a spray-and-rinse shortcut.
- Will not lift white oxidation, and the price per bottle splits opinion on value.
Built for: patios and decks where composite meets pavers and you want one warranted, biodegradable cleaner covering both.
Not the answer for: chalky, oxidized surfaces or anyone hoping to skip the brush.
Know the Specs
pH level and formula base
pH tells you how acidic or alkaline a cleaner is, and on natural stone acid is the enemy — it can etch the surface and leave a dull patch. A pH-neutral cleaner sits in the safe middle band, so it cleans without eating into the stone, which is why it is the default for anything polished, sealed or interior. Peroxide and bleach formulas are stronger outdoor tools; they lift algae and mildew well but are best reserved for unsealed exterior pavers you can rinse away from plants.
Concentrate yield and coverage
Yield is how much cleaning solution a bottle makes once diluted — the number that actually decides cost per patio. A ready-to-use spray is already mixed, so it suits touch-ups and countertop wipes. A concentrate that dilutes into many gallons covers a driveway or paver patio from one jug. When you compare bottles, look at the square feet covered per bottle rather than the jug size alone, and match the yield to the area you actually clean.
Clean versus clean-and-seal
Some cleaners carry a small amount of sealer so the surface keeps its water and oil resistance after the wash — helpful on honed counters and polished stone. If your stone is already sealed, a plain neutral cleaner avoids building up a hazy film over time. Check whether your bluestone is sealed before choosing a clean-and-seal product.
Pressure-washer compatibility
Outdoor concentrates are often designed for pressure washer tanks and detergent attachments, with anti-corrosive formulas that protect the pump. A manual bucket-and-brush dilution works for smaller jobs. If you plan to pressure wash, check that the cleaner is built for your machine and keep the surface wet until you rinse, so no residue dries in place.
