A mixture of one part bleach with three parts water is the most common cleaning agent used to remove mold from pavers.
Vinegar is a safe and effective mold removal solution, but if this method doesn't prove to be effective, then a heavier-duty weapon may be deployed: bleach. One cup of bleach mixed with a gallon of water should do the trick. Simply combine the bleach and water in a spray bottle and apply directly to the pavers.
Similar to cleaning pavers with muriatic acid, avoid an intense concentration of bleach, as it can damage the pavers.
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.
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.
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.
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.
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.
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.
You can also choose to scrub your patio with oxygen bleach like OxiClean. Add two scoops of oxygen bleach to a gallon of water. Cover the bricks. Allow it to sit for 10 minutes.
Leave the white vinegar for 1 hour or so to let the vinegar work its way into the paver slabs. Spray the surface with soap and water, then scrub off. Rinse with warm water, then let dry. You may repeat the process if there are stains left.
Vinegar and water.
This is an excellent option if you're looking for a more natural way to clean your pavers. Vinegar is known for its cleaning properties, and you can use it as a household cleaner on a variety of surfaces. Plus, it's more eco-friendly than other cleaning options since you're not using harsh chemicals.
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.
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.
Whether your patio is sealed concrete or cement, or even sealed concrete pavers, a bleach and water solution makes it easy to clean away built up soil, stains from leaves and pollen, mold, mildew and algae.
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.
Oxyclean will do the trick here! Use 4 scoops per gallon of hot water and soak the surface for 15 minutes. Scrub with a brush and rinse.
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.
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.
Wash patio slabs with white vinegar
This eco-friendly solution is made up of equal parts vinegar and water, which is then left to soak into the patio to correct any discolouration and also remove tough marks. You should first move all plants and furniture out of the way, then sweep the area to remove any moss.
Cleaning concrete with vinegar will not damage it! However, saturating concrete for an extended period will damage the cement that binds concrete together. Over time, vinegar erodes the concrete itself, so be careful.
