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.
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.
Apply the bleach solution
Allow the bleach solution to contact the surface for up to 15 minutes. Work in smaller sections if the patio is too large to finish in that time.
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.
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.
Pour ⅓ cup of Clorox® Disinfecting Bleach into 1 gallon of water in a plastic bucket or container. Apply bleach solution using a brush or broom on horizontal surfaces, and a sponge or mop on vertical surfaces. Heavily soiled surfaces may require additional scrubbing. Wait 6 minutes for disinfecting.
Use a mild grease-cutting detergent such as Dawn or Ajax dishwashing liquid mixed with water and a natural or synthetic bristle scrub brush to help brighten the patio surface. NOTE: Never use a wire brush as it can leave rust stains and scratch the concrete surface.
After disinfection with bleach solutions, surfaces should be rinsed and dried. Bleach can be irritating to skin and mucous membranes, so any residue should be removed prior to returning animals to the environment.
Yes, vinegar is an excellent concrete cleaner. This solution can strip surface-level messes from concrete. Due to its acidic properties, vinegar can be a powerful tool for breaking down offensive materials such as dirt, stains, and bacteria.
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.
For lightly soiled concrete, you can remove dirt by using bleach mixed with water. Add 1/8th cup of liquid dishwashing detergent to the solution and pour it into a spray bottle. Spray the solution onto the surface, and let it sit for a few minutes. Scrub with a nylon-bristled brush.
Will Vinegar Damage Concrete? Cleaning concrete with vinegar will not damage it! However, saturating concrete for an extended period will damage the cement that binds concrete together. Over time, vinegar erodes the concrete itself, so be careful.
Use bleach for heavy-stained slabs
Dilute half a bucket of bleach with equal parts water, applying evenly to your green-tinged patio. You should leave the solution to work for ten minutes before rinsing thoroughly with clean water, repeating the method for stubborn algae.
Leave the Bleach on the Pavers
Allow the bleach to sit on the pavers for about 10-20 minutes. This will help to disinfect and clean the surface. It will also help remove any stains that are tough to remove and mold.

However, when chlorine is present in a water-based solution, it can permeate through concrete and reach the steel bars giving the concrete structural support. The chlorides corrode the metal framework, endangering the skeleton of your concrete floor.
If you need to get rid of rust from concrete, your best bet is to use some WD-40 Multi-Use Product, and some elbow grease. WD-40 is specially formulated to be a penetrant, so when you spray it on a rusted surface, it gets to work right away by getting under the rust.
Vinegar Solution
Vinegar is the perfect option in such cases. Used similarly to bleach, vinegar is known to kill many species of fungus including harmful mold. Spraying a vinegar solution (1 cup of vinegar per gallon of water) onto the surface, saturating it fully, should kill most strains of mold.
What happens if you don't dilute bleach? You might damage what you're trying to clean, according to Johnson. Full-strength (non-diluted) bleach can be damaging to the surface and be harsh on your skin.
Bleach can irritate the skin and eyes. Breathing in bleach over a long period of time can increase your risk of cancer. A dangerous gas can be formed when bleach is combined with certain chemicals (like ammonia). Bleach causes the buildup of chloroform in the air.
Say, for example, you're mopping the floor with a bleach solution and leave the room for a moment. Your dog or cat may lick the wet floor, or even take a drink from the mop bucket. And even after the floors have dried, your pet may still get sick from licking it; bleach residue is still toxic even when it's dry.
The Liquid peroxide cleans, refreshes, and brightens concrete, tile, and grout without leaving watermarks or residue in contrast to other cleaning chemicals.
For an environmentally friendly cleaning a biodegradable soap is best. To do this, first dissolve the soap in lukewarm water, then apply it to the surface and leave the mixture for 20 to 30 minutes. Then scrub the surface with a scrubbing brush or a hand brush.
