Dilute white vinegar with water in a bucket, at Walmart (a 50:50 solution is fine), and apply this natural, eco-friendly cleaning solution to the paving slabs with a firm brush and rinse thoroughly.
Water and mild dish soap is a popular cleaning solution because it's easy to find at home and it won't damage brick, but it will tackle stains. The BIA recommends using hot water for surface cleaning with a detergent. White vinegar and water, another common household cleaner, can also be used on mildew.
Fill up a gallon sized bucket with water and add about 16oz of dish detergent. Mix the soap into the water thoroughly. Once your cleaning solution is ready, gently pour some onto your paver surface, working in small areas at a time. There are also specific cleaning solutions.
Usually, hosing them down once a month is sufficient. Use soap and water, if the pavers are still dirty after sweeping and water hosing, make a solution of soap and water. You can use dish soap, laundry detergent, or any type of general-purpose cleaner. Never use bleach on your pavers, as it can damage the surface.
To clean paver slabs, you can use a detergent, such as Dawn, or a vinegar-water solution that is gentle enough to effectively clean without causing damage to your concrete pavers.
White vinegar is good for cleaning pavers, though it's also acidic enough to erode the stones' surface. Diluted vinegar can be used safely to clean paving stones, though it should be used sparingly and infrequently to protect your paving from damage.
Use a specialist cleaner
Try a specialist cleaner like Wet & Forget, at Walmart, which you spray onto the surface of the paving and leave. It can also be used on steps, fountains, patio umbrellas and other smaller outdoor areas. It's bleach-free and non-acidic but will remove mold, moss and grime without any scrubbing.
It is common to mix bleach with water; however, you can also add other ingredients to make it more effective. Similar to cleaning pavers with muriatic acid, avoid an intense concentration of bleach, as it can damage the pavers.
On the other hand, baking soda is useful because it is slightly abrasive, which is excellent for the rough surfaces of paving slabs. When it is mixed with water, it can dissolve dirt and grease, and like vinegar, you'll only need a brush or broom when cleaning.
Scrubbing Brush and Bucket
Ahhhh the good old-fashioned scrubbing brush. It's been around for such a long time as it genuinely works. When those bristles are passed over the target surface vigorously enough, it'll remove most dirt and stains.
Apply the Simple Green solution. Allow the product to soak for a minute or so on heavy soils and greasy spills. Scrub, if necessary. Scrubbing with a soft bristle brush or non-abrasive scrubbing pad provides agitation that will help to loosen soils and will ensure a thoroughly clean, residue free surface.
Pressure washing is one of the most effective ways to clean your pavers. However, if not done properly it cause permanent damage and deterioration to the surface. Excessive water pressure may remove dirt and grime build-up but it can also eat away at the material.
If your deck is made from concrete, pavers travertine, brick, stamped concrete or composite decking, you can clean and refresh it for summer using OxiClean™ Versatile Stain Remover.
OxiClean is a powerful concrete cleaner that works well on various materials, including pavement and grout. This concentrated solution provides excellent cleaning without leaving residue.
The simplest path to reviving tired pavers is to apply an acrylic-based semitransparent concrete stain, such as Behr Premium Semi-transparent Concrete Stain ($27/gal.; Home Depot) or Valspar Semi-transparent Concrete Stain ($28/gal.; Lowe's).
Simply put, black stains on flagstones are caused by certain types of mold and mildew. These fungi find their way onto the stones either from their spores landing on the stones or from simply extending onto the stones from patches of mold or mildew right beside them—a pretty common occurrence for garden pavers.
Remove limescale buildup with a 50:50 ratio of water and white vinegar. Spray the solution on the surface of your pavers and let it sit for a good 30 minutes before scrubbing with a scrubber brush and rinsing the pavers off.
A mix of water and vinegar is a great combination to remove stubborn dirt and stains. If you want even better results, use this mix with a cleaner solution specific made for pavers or soap and water. Just remember to plan your cleaning on sunny days because if it rains, you might need to redo all the work.
Although bleach is great at the whitening effect, you can use peroxide to achieve this. Hydrogen peroxide is an oxygenated bleach. It is safe for plants, so when you rinse this solution, it won't harm anything. It works together with the dish soap and baking soda to remove dirt and whiten dirty concrete.
