Mild detergent and water.
Mix some mild dish soap with water in a bucket to create suds, then use a brush or a sponge to scrub the surface of the pavers. If your pavers are textured or have intricate designs, this cleaning method can be gentler than a power washer.
Generally, interior pavers that have been grouted and sealed just need to be swept, mopped, and spot-cleaned as needed with a gentle, non-acidic multipurpose cleaning solution, such as Enviro Klean All Surface Cleaner or Light Duty Concrete Cleaner.
The pressure washer in combination with a dirt cutter is an excellent option. This removes not only weeds and moss from the surface, but also from indentations. Keeping up with this type of cleaning means that there is less time for weeds to grow. It also helps to maintain the beauty of the paving stones' 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.
Yes, using vinegar is a good choice for cleaning pavers and very effective as well. Once vinegar is a non-toxic and biodegradable solution, it is a great way to clean your pavers without resorting to chemicals, which is safer, since you don't harm your plants, pets, or the soil.
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.
Cleaning your pavers with bleach has a lot of benefits: Disinfecting the Surface: Bleach is an effective disinfectant and can kill any bacteria or mold on the surface. This will help to prevent any health hazards from occurring. Removing Tough Stains: Bleach is also effective in removing tough stains from the surface.
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.
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.
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.
If you are prepared to use chemicals to remove algae, lichen and moss from your pavers, it is important that you use plastic sheeting to protect other plants in the vicinity. A solution of one cup bleach to four litres of water should do the trick.
Try Concrete Stain
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).
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.
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.
Use a Pressure Washer
If this is not the case, pressure washing is often quite effective in removing mold and algae from pavers, bricks or concrete. If you do not have a pressure washer, you can purchase one relatively inexpensively to have on hand for this and future projects.
You can't cover your patio with copper sheets, but you can spray on a liquid solution of copper that will soak into the top surface of the concrete pavers. This copper will stop the growth of the pesky green and black organisms in their tracks. The easiest way to apply the copper is to buy copper sulfate crystals.
Dish soap and water: Dish soap is a degreaser, and it works well to clean oily and grimy concrete. Create a cleaning solution of warm water and few drops of dish soap and apply it to the surface. Let it sit for a while, then mop the patio and rinse it with fresh water. Repeat the process as many times as needed.
