There are a few ways you can remove algae from your green pavers, walls and fencing, some more effective than others. The simplest and most effective way is with HG algae and mould remover.
If vinegar does not do the trick, you can also try mixing about a cup of bleach for each gallon of water and using this as your mold-killing spray solution.
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.
Vinegar or bleach are two easy to find cleaning solutions that kill moss so that you can wash it away. You will want to mix either bleach or vinegar with water in a 1 to 1 ratio. The 50/50 mixture of water and bleach/vinegar is gentle enough to clean brick and works well against moss.
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.
Spraying with a vinegar solution
is an effective way to eliminate moss on pavers without damaging nearby plants and grasses. Mix one part water with three parts vinegar, and spray the mixture directly on your pavers. This will help kill any moss growing on them as well as prevent new growth for up to a month.
You can use vinegar as you would a moss killer on patio pavers to remove it. Simply wait for a dry spell, dilute white vinegar half and half with water, then spray on to the moss. Leave for a few days to allow the moss to die off, then brush it off and compost.
The best way to control moss on your pavers is to keep them clean, dry, and wash them several times a season. You can treat them regularly with a 10-15% bleach solution as a preventative measure. Although sealing your pavers will not prevent moss, it can limit the amount of moisture in the pavers and joints.
If used incorrectly, muriatic acid can damage the surface of porcelain pavers. It is important to dilute the solution according to the manufacturer's instructions and to rinse the pavers thoroughly after using the solution.
Yes, you can pressure wash your pavers. But while using a pressure washer at a basic level is simple, ignorant and inexperienced users can easily damage their pavers by using a stream that's too powerful, by holding the wand too close to the pavers, or by falling into any number of other rookie mistakes.
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.
In the same way that baking soda can be a spot treatment for black algae, household borax does the same for blue and green algae. Simply use the borax to scrub away algae that's sticking to your pool walls, then use the brush to dislodge it. Follow up by vacuuming up or scooping out the free-floating algae.
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.
Iron Sulphate:
Iron sulphate is very effective against moss – the correct dose kills the moss within four days. After use, the moss turns dark brown and dies off. Iron sulphate is also often added to granulated fertilisers as a micronutrient for the lawn, making it easy to spread.
Therefore, we'd really only suggest you grow moss between pavers if your patio is something that is largely decorative and used infrequently. Or, around generously spaced stepping stones rather than in between smaller joints of a patio, walkway or driveway.
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.
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.
Baking soda has low-abrasive properties, making it an excellent cleaning material for stuck-on grime and tough stains. Additionally, baking soda is absorbent, allowing it to absorb oils from the surface of the pavers, especially freshly oil spill on 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.
