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.
To clean your pavers with vinegar, mix equal parts of water and vinegar in a bucket, let it sit on the pavers for an hour so that the vinegar has time to work, then scrub the surface with a brush or a sponge. Make sure you choose white vinegar for household cleaning, as other types of vinegar can stain.
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.
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.
Pour baking soda on the stained spot, then add a bit of warm water. You can add some detergent or white vinegar for a stronger vinegar solution. Let the mixture sit for at least 1 hour. Scrub the top of the pavers, with extra attention to the gaps between the stones or bricks.
Whilst vinegar will not directly dissolve concrete itself, but it will degrade the cement that binds your concrete slabs or flags together. Extended exposure to vinegar will also cause any polish or sealant on your pavers to erode over time, leading to bleaching, stains and weathering.
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.
Before cleaning, we recommend decluttering and sweeping your patio so it is clear of any debris or dirt. Once your patio is clear, pour the vinegar solution over the areas that need cleaning and leave for 20 minutes. Once the time is up, give it a good scrub with a gardening brush and rinse it away.
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.
Remember that vinegar can only be used for a short time on finished surfaces. Not only does it kill algae, but it eats away at polished cement if you leave it on the cement for too long. Vinegar can be used for longer periods on unfinished cement to remove algae, and it serves as an excellent cleaning agent.
Similar to cleaning pavers with muriatic acid, avoid an intense concentration of bleach, as it can damage the 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.
Vinegar is acidic and will eventually kill most broadleaf weeds, but the acid will kill the leaves before reaching the root system, and the weeds may grow back quickly. For longer-lasting removal, mix 1 cup of table salt with 1 gallon of vinegar. Salt dries out the weed's root system.
Glyphosate, the ingredient in Roundup and other products, is translocated from the leaves to the roots of a weed. Vinegar is not translocated. It is true that 5% vinegar (acetic acid) will kill young, tender weeds but it does little damage to established weeds.
Vinegar with a higher concentration of acetic acid tends to control weeds more effectively. Household vinegar is generally 5% acetic acid. Some herbicidal vinegar products are 20% or 30% acetic acid. In general, 20% or 30% acetic acid is more effective because it more completely kills young leaves and growing points.
The set time for vinegar can be up to 30 minutes. For example, to clean the insides of food-stained pots and pans, soak them in a mixture of one-half cup of white vinegar diluted with one gallon of water for 30 minutes. Then rinse in hot, soapy water.
Pouring vinegar on soil will lower the pH, and alkaline soil is essential for growing blueberries. But you'll need a lot of it because it's a weak agent. “Vinegar is not effective with lowering soil pH,” says Fornari. “Aluminum sulfate is, and research backs that up.
Almost Indefinite Shelf Life
Vinegar is a fermented product and has an “almost indefinite” shelf life according to the Vinegar Institute. “Because of its acid nature, vinegar is self-preserving and does not need refrigeration.
Use Vinegar or Bleach
If you are going to try this approach to remove mold or algae, first try a mixture of white vinegar and water to spray down the area and kill the mold.
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.
