Whether it's sticky candy, saucy ketchup, or grease drips from your last cookout, liquid dish soap can do the trick. Put atop the stain and let penetrate for 20-30 minutes, then scrub and rinse off with hot water.
SOAK WITH BAKING SODA
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.
Baking soda is an amazing household cleaner, and it can work really well on your pavers too.
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.
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.
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.
Similar to cleaning pavers with muriatic acid, avoid an intense concentration of bleach, as it can damage the pavers.
For human-made colored concrete paving slabs or concrete pavers, we don't recommend the use of bleach for cleaning. That's because the substance could fade your paver colors if regularly cleaned with bleach over a long period. However, if you don't mind this, then there will be no problems.
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.
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.
Mild detergent and water.
Mix some mild dish soap with water in a bucket to create suds, then use a brush or a sponge to scrub the surface of the pavers. If your pavers are textured or have intricate designs, this cleaning method can be gentler than a power washer.
Dish soap and water: Dish soap is a degreaser, and it works well to clean oily and grimy concrete. Create a cleaning solution of warm water and few drops of dish soap and apply it to the surface. Let it sit for a while, then mop the patio and rinse it with fresh water. Repeat the process as many times as needed.
Will Vinegar Damage Pavers? Yes, vinegar is NEVER safe to use on pavers. It can cause a lot of damage, and you may have to replace a lot of the pavers if you try this. I know that vinegar is often used for household cleaning projects, but when it comes to your patio, it's a big no!
Exposure to sunlight is the primary reasons why pavers fade. The sun causes fading of any pigmented item, from fabrics and paint to the pigments in the stones. You might notice some mottling of the color of your paving stones as the years go by. This is because the pigments do not penetrate into the aggregate.
You may also use Oxyclean mixed 4 scoops to a gallon of hot water. Let soak for 15 minutes and then scrub with a nylon bristle brush, then rinse. Caulking - Scrape off excess and scrub with a poultice of denatured alcohol. Rinse with hot water and detergent.
If your deck is made from concrete, pavers travertine, brick, stamped concrete or composite decking, you can clean and refresh it for summer using OxiClean™ Versatile Stain Remover.
Regular Soap and Water
A solution of regular dishwashing soap or hand soap is simple to create, and it will remove mild to moderate dirt, stains, and grease. Just mix your soap and some warm water in a large bucket and you're ready to start cleaning.
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.
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.
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.
Then, move to a household cleaner. A dish soap, like Dawn, is a safe place to start. The surfactants in dish soaps are designed to remove oil and grease, they're gentle enough to be used without issue on your pavers. In a bowl or bucket, mix the soap with water and pour it onto the stain and agitate.
