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.
Bleach: This alkaline solution may be effective for other household uses, but it can discolor concrete pavers that have been colored or stained.
Cleaning pavers with bicarbonate soda and vinegar
Fill the bucket with lukewarm water and then add the bicarbonate soda, making sure it dissolves properly. Then add a little bit of white vinegar. Pour the solution onto the stained areas on your paver surface and use the scrubbing brush to apply it thoroughly.
First, you'll need to make sure that there's no run-off of the bleach onto any surrounding plant life. Plants that come into contact with bleach will die. Second, bleach isn't suitable for man-made concrete slabs – only natural paving stones. Bleach will fade artificial slabs over time.
Apply the bleach and water to the wet paving slabs
Brush the solution to make sure you get an equal coverage of the cleaner. Make sure you brush the cleaner into all corners of the paving slabs. Once applied leave the cleaner on the surface for 10 -15 minutes.
Use Bleach
But that's not all; chlorine bleach can also be used for cleaning the concrete driveway. Of course, you should dilute it with equal parts of water or a 1:1 ratio. With the mixture ready, spray it on the driveway, allowing it to sit for 10 minutes. Then, use a stiff brush before rinsing with clean water.
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.
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.
As a gentler cleaner, bleach can't harm concrete's durable material. Aside from being an effective cleaner and stain remover, it also acts as a disinfectant to the concrete surface.
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.

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.
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.
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.
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.
In fact, vinegar removes mold from concrete better than bleach. Bleach will only remove the top layer of mold, causing the mold to return.
When bleach is left to air dry on floors and is not rinsed away, it can leave behind bleach crystals after the bleach evaporates. Sodium hypochlorite will break down into salt and water when left to do so. Since undiluted bleach is mostly water to begin with, once the floor dries, salt crystals will be left behind.
Bleach is commonly used to whiten concrete and is very effective at doing so if the initial stain is removed beforehand. Bleaching stained concrete white prepares it for any additional coloring treatments that you may wish to apply in the future.
