There are a few different cleaners you can use to clean your brick pavers. The safest cleanser is a mixture of warm water and a mild household cleaner, like dish detergent.
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.
White vinegar and water, another common household cleaner, can also be used on mildew. For brick pavers that get a greenish or blackish hue from moss and lichen, damp shady environments, or water run-off, the BIA recommends bleach and water (mixed with a one-to-one ratio) or commercially available biocide treatments.
There are useful tools for cleaning paving stones, such as joint scrapers, sweepers, and pressure washers. In addition, pavers can be cleaned with a small pickaxe, broom, and garden hose.
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.
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).
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.
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.
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.
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.
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.
Baking soda is an amazing household cleaner, and it can work really well on your pavers too.
3) USE A CLEANER FIRST
I used a bleach-free pressure washer concentrate and sprayed it over each section to help loosen the grime before going at it with a higher pressure nozzle. It didn't take long to apply and helps get those stubborn mildew stains out.
Simple Green is one of the best cleaning products for dirty pavers. It doesn't have any harmful chemicals that could possibly warp your precious driveway. Less chemicals mean there's a less likely chance your paver stones will change to a weird-looking color.
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.
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.
Depending on the material of the paver (non-coloured concrete is safe), CLR may be suitable. Always spot test in an inconspicuous area first. Make sure the pavers are not coloured, stamped, sealed or coated.
When properly installed, brick pavers are known to last you a lifetime. The average lifespan of a good quality brick pavers installation typically falls between 50 and 100 years. It may last longer in some cases. When it comes to measuring strength and durability, brick pavers win the race.
Can you power wash pavers? Power washing (also known as pressure washing) is also a very effective method by which you can remove dust deposits and various stains from your pavers. Just make sure that the water jet is not directed directly at the joints between the paving stones.
As mentioned earlier, it is very easy to restore the color to brick pavers. Wet-look sealers are highly recommended because they help restore some of the original colors and prevent future fading, but without changing an existing color.
If you don't have the supplies for the ammonia mixture, you can also use bleach or hydrogen peroxide to remove mold, mildew, and stains. Remove dirt and debris using the broom. Put on safety gear. Pour ½ cup of bleach or hydrogen peroxide in a spray bottle with 3 cups of water.
WD-40 may remove paint stuck to brick if applied directly and in large quantities, allowing it to sit on the surface for a few hours.
