Concrete is prone to many types of dirt and stains, and it’s incredibly susceptible to be soiled from dirt, algae, mildew, mold, and other environmental elements. Concrete driveways suffer from oil-based stains and other stubborn problems. Bleach can be used as a preparatory cleaner on some stains, and it can remove dirt and kill algae in other areas.
Types of Concrete Surfaces
There are several different types of concrete surfaces that can be cleaned using bleach, which includes driveways and walkways, and there are also other outdoor concrete surfaces that need periodic cleaning. Basement walls that have accumulated mildew or mold can be easily cleaned using a bleach spray solution. Water fountains run the risk of growing dirt, grime, mold, and mildew and can be cleaned with bleach. Retaining walls, patios, statues, and birdbaths all could benefit from a bleach cleaning from time to time.
Why Clean Concrete with Bleach?
A simple solution of household bleach poured onto the problem area followed by a hot water rinse can remove dirt, grime, mold, and mildew. In certain instances, using a scrubber or a broom with a bleach solution can release embedded dirt. Since concrete is porous, it will retain both odors and stains. If there is a pungent stench that’s permeating from your concrete surfaces, then you will have to seal the concrete to eliminate the odor permanently.
When it comes to oil stains and other stubborn stains, pre-washing the outdoor concrete surface with bleach will prepare the area for a further power wash. Bleach can be diluted to the strength that is needed for the particular project you are working on. However, this won’t be necessary in most cases.
Step-by-Step Guide to Cleaning 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. Don’t use a metallic brush because it will leave metal bits on the concrete that rust and stain the patio. Protect any plants that surround your patio, as bleach will kill your plants. Rinse the bleach off with a hose.
If those stubborn stains aren’t coming off, mix oxygen bleach with water to make a paste that’s the same consistency as peanut butter. Apply to stained areas and let it sit for an hour. Scrub with your nylon-bristle brush.
Safety Precautions for Cleaning Concrete
Always remember not to mix bleach with ammonia, as this will result in toxic gas. Before you mix bleach with any other product, consult the product information for specific chemical information. Keep in mind that household bleach is used as a weed killer, so it most likely will kill any grass that gets saturated. Be careful to not get any bleach on the soles of your shoes, which can bring toxins into your home.
After years of use, your concrete will experience more problems than just staining. When the day that your concrete becomes damaged comes, you’ll need experts to fix your concrete. Contact Hard Rock Concrete Coatings if you require a concrete repair.
