Unfortunately cleaning is not a one-size-fits-all process for pavers. For example, masons will use muriatic acid on clay brick to remove mortar. However, muriatic acid could do serious damage to a concrete paver.
Cleaning effloresence and stains from pavers is easily done using an acid wash which requires only a broom, hydrochloric acid and water.
Acids and acid-based cleaners can, and all-too-often do, cause devastating damage to the appearance of some types of paving. However, being wise after-the-fact is all too easy.
Always fill the watering can with water first and then add the acid. After you clear a space, pour the mixture from a watering can over a small, manageable area. After about three minutes, generously hose off the muriatic acid solution before it can start to damage your pavers.
Dry brushing with or without application of clean sharp sand. OR High pressure water jetting with or without detergent. OR Apply fungicides. Use ordinary bleach or calcium chloride followed by sodium hypochlorite dissolved in water (1kg in 5 litres) then scrub with stiff brush.

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.
Over time, it can destroy concrete as the acid weakens its structure. This will cause scaling, pitting, peeling, and cracking. If the acid wash gets into the soil, it will evaporate on the surface but remain beneath the surface (just like it does with concrete).
To clean and etch concrete, mix one part muriatic acid to 10 parts water. Brush or spray the acid solution on the concrete, wait eight to 10 minutes, then neutralize the acid by spraying the surface with a mixture of one cup of ammonia in one gallon of water.
Scrub the acid solution: Once the solution is applied, lightly scrub it into the concrete with a push broom or long handled scrub brush. This helps to create a uniform etch of the concrete. Let the solution sit from 2 – 15 minutes while it continues to fizz and bubble.
Acidic cleaners: Harsh, acid-based cleaning products and stain removers can damage the seal and finish of your concrete pavers. Bleach: This alkaline solution may be effective for other household uses, but it can discolor concrete pavers that have been colored or stained.
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.
Start by mixing a solution of 1 part muriatic acid to 10 parts water in a bucket or spray bottle, then soak the stained area. Wait about 10 minutes and then spray the area with a solution of 1 cup of ammonia to 1 gallon of water to neutralize and clean the acid.
Dilute white vinegar with water in a bucket, at Walmart (a 50:50 solution is fine), and apply this natural, eco-friendly cleaning solution to the paving slabs with a firm brush and rinse thoroughly.
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.
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.
Muriatic acid will quickly liquify most metallics, consisting of iron, copper, and light weight aluminum. It can easily additionally diffuse cement, rock, mortar, as well as grout. Additionally, muriatic acid will take out blemishes from rugs as well as cloth.
No, you can't pour muriatic acid outside.
Doing so would kill plants and harm the soil, and the acid could leach into groundwater.
When cleaning with basic pH chemicals such as sodium hypochlorite, you remove dirt, mold, and algae from surfaces easily, but do not get the brightening effects acidic pH chemicals, such as muriatic acid, provide. Muriatic acid can provide that bright white look that new concrete often has.
areas should be missed, ensuring that the reaction is visible over the entire surface. Avoid walking on areas that have been worked already. The acid stops reacting with the concrete after approximately 30 seconds so there is no need to scrub the surfaces for too long.
Any concrete that is not properly neutralized will begin decomposing immediately. It may take time for the damage to reach the surface where you can see it, but it is happening and is usually irrepairable.
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.
You can use a pressure washer on your patio pavers if you want to clean stubborn stains or mildew from them. However, be very careful when doing this! Use a gentle spray and avoid letting the water run down the sides of your pavers, especially if they're set in the sand rather than mortar.
Specially designed narrow-bladed weeding tools – sometimes called 'dandelion weeders' – for tackling such weeds are the most effective. More generally, a 'block paving knife' can be run along between pavers to sever most weeds. A wire-bristled 'block paving brush' is good at removing moss and the smaller weeds.
