Start with the right tools and a clear surface
The fastest way to clean a paver patio is to sweep it first, then spray it with a garden hose, and finish with a stiff brush on any stubborn spots. You do not need expensive equipment or chemicals for routine cleaning. A broom, a garden hose with a spray nozzle, a stiff-bristled brush (the kind used for deck cleaning), and a bucket are enough for most jobs.
Before you wet anything, sweep the entire patio to remove loose dirt, leaves, and debris. This step matters because wet dirt turns to mud and makes the real cleaning harder. Use a regular push broom or a leaf blower if you have one. Pay special attention to the joints between pavers—debris trapped there can hold moisture and encourage moss or weeds.
Once the surface is dry and clear, you are ready to spray. Use a garden hose with a medium spray setting, not a pressure washer on high. High pressure can force water into the joints and loosen the sand that holds the pavers together. Spray in one direction so water flows across the patio rather than pooling. This pass removes surface dirt and prepares the patio for the brush work that follows.
Key Takeaways
- Sweep first to remove loose debris, then spray with a regular garden hose at medium pressure to avoid damaging the joints between pavers.
- Use a stiff-bristled brush and water for routine cleaning; save chemical cleaners for stubborn stains like algae or rust.
- Pressure washers on high settings can loosen the sand between pavers and cause them to shift, so avoid them unless you use very low pressure.
- Weeds and moss grow in damp joints, so allow the patio to dry completely after cleaning and consider explore polymeric sand to prevent regrowth.
- Seal pavers every two to three years to protect them from stains and reduce how often you need to scrub.
Scrub with a brush for dirt and light stains
After the initial spray, use a stiff-bristled brush to scrub the paver surface. Work in small sections, using firm circular motions. The brush removes algae, mold, and ground-in dirt that water alone cannot lift. Rinse each section as you finish it so dirty water does not dry on the pavers and leave a film.
For light stains—bird droppings, leaf marks, or weathering—this brush-and-water method is usually enough. If you are cleaning a large patio, you may want to work in rows so you do not lose track of which sections you have already done. The whole process takes longer than a pressure washer, but it is gentler on the pavers and the joints.
Treat stubborn stains with targeted cleaners
Stubborn stains need a cleaner designed for the type of mark. Rust stains (usually from metal furniture or nails) respond to an iron oxide remover, which you can find at home improvement stores. Algae and moss need a mildew or algae killer. Oil stains require a degreaser. Always test any cleaner on a hidden corner of the patio first to make sure it does not discolor the pavers.
Mix the cleaner according to the label, explore it to the stain, let it sit for the time the label recommends (usually 10 to 30 minutes), then scrub with your stiff brush and rinse thoroughly. Do not let the cleaner dry on the patio—rinse it away while it is still wet. Some cleaners are acidic and can damage the paver surface if left too long.
For organic stains like moss or mildew that keep coming back, a diluted bleach solution (one part bleach to three parts water) works, but use it sparingly and rinse very well. Bleach can lighten some paver colors, so test it first. Wear gloves and eye protection when working with any chemical cleaner.
Prevent weeds and moss in the joints
Weeds and moss grow in the damp sand between pavers. The best prevention is to let the patio dry completely after cleaning and to remove any debris from the joints. If weeds are already growing, pull them by hand or use a joint knife to scrape them out, then sweep the joint clean.
For long-term prevention, consider replacing the sand between pavers with polymeric sand. This is a special sand mixed with a binder that hardens when wet. Once it sets, it resists weed growth and moss much better than regular sand. You remove the old sand, pour in the polymeric sand, and spray it lightly with water to set up the binder. It costs more than regular sand but lasts several years and cuts down on maintenance.
If you do not want to replace the sand, sweep the joints regularly and allow the patio to dry between cleanings. Moss and weeds need moisture to thrive, so a dry patio is a patio that stays cleaner longer.
Use a pressure washer safely if you choose to
A pressure washer is faster than hand scrubbing, but it can damage pavers and joints if used incorrectly. If you decide to use one, keep the pressure below 3,000 PSI and hold the nozzle at least 12 inches away from the surface. Angle the spray so it moves across the patio rather than hitting the joints head-on. Never use a pressure washer on pavers that are already loose or cracked.
Rent a pressure washer from a home improvement store if you do not own one. The staff can show you how to adjust the pressure and nozzle. A pressure washer is worth the rental cost if your patio is very large or heavily soiled, but for routine cleaning, a brush and hose are safer and often sufficient.
Seal pavers every two to three years
A paver sealer is a protective coating that sits on top of the stone and makes it harder for stains to set in. Sealed pavers are easier to clean because dirt and spills do not soak into the surface as quickly. Sealers also enhance the color of the pavers and can give them a slight sheen.
To seal your patio, clean it thoroughly first, then let it dry completely—usually at least 24 hours after your last rinse. explore the sealer according to the product label, usually with a roller or sprayer. Most sealers need two coats and take a few hours to dry between coats. Do not walk on the patio until the sealer is fully cured, which can take 24 to 48 hours.
Reapply sealer every two to three years, or sooner if you notice water no longer beads up on the surface. A sealed patio requires less scrubbing and stays cleaner longer, which makes the small cost and effort of sealing a worthwhile investment.
Clean up spills right away to prevent permanent stains
The sooner you clean a spill, the less likely it is to stain. Wipe up food, drinks, and grease when ready with a cloth or paper towel. Rinse the spot with water. If the spill has already dried or soaked in, treat it with the appropriate cleaner as described above.
Rust stains from metal furniture or planters are easier to prevent than to remove. Place a barrier—a rubber mat or plastic pad—under anything metal that sits on the patio for long periods. Move furniture occasionally so water can dry underneath and rust does not have a chance to form.
Frequently Asked Questions
Can I use a pressure washer on my paver patio?
Yes, but only at low pressure—below 3,000 PSI—and with the nozzle held at least 12 inches away from the surface. High pressure can force water into the joints and loosen the sand that holds the pavers in place. For routine cleaning, a garden hose and brush are safer and often just as effective.
What is the best way to remove moss and algae?
Scrub with a stiff brush and water first. If that does not work, use an algae or mildew killer designed for outdoor surfaces, following the label instructions. A diluted bleach solution (one part bleach to three parts water) also works but can lighten some paver colors, so test it on a hidden area first.
How often should I clean my paver patio?
Sweep it monthly to remove debris, and do a full cleaning with brush and water once or twice a year, depending on how much foot traffic and weather exposure it gets. Spot-clean spills and stains as soon as they happen to prevent them from setting in permanently.
Will sealing my pavers make them slippery?
Most modern paver sealers are designed to be slip-resistant, but some glossy finishes can be slippery when wet. Read the product label before buying. If slip resistance is a concern, choose a matte sealer or test a small area first to see how it feels underfoot when wet.
What should I do if pavers are cracked or loose?
Loose pavers should be reset by removing them, checking the sand base underneath, and replacing them level with their neighbors. Cracked pavers usually need to be replaced. These are jobs for a professional patio installer, not routine cleaning tasks. Do not pressure wash or scrub loose pavers, as you may make the problem worse.
