How To Clean And Seal A Stamped Concrete Patio (New or Old)

For easy cleaning, use Scotts® Outdoor Cleaner Plus OxiClean Concentrate to break up dirt and stains caused by moss, mold, mildew, and algae. Its also safe to use around plants, grass, and fabrics.

  • Mix and apply according to label directions. Determine the best water-to-cleaner ratio based on the amount of dirt and staining on the concrete. Apply the solution to the surface and let it sit for 5 to 10 minutes. Be sure to keep the concrete wet during this time.
  • Scrub the surface clean. Use a natural bristle or plastic scrub brush, as metal brushes can shed tiny fibers that work into the porous surface, eventually forming rust spots. A deck brush is an ideal concrete scrubbing tool because it lets you scrub while standing.
  • Use a power washer for large areas. If you have a large driveway or patio to clean, a pressure washer will make the job much easier . Unlike many other outdoor cleaners, Scotts® Outdoor Cleaner Plus OxiClean Concentrate can be used in power washers. Be sure to follow the directions on the label.
  • Rinse the surface. Spraying off the surface after scrubbing will wash away dirt and foam, leaving it nice and clean.

Removing Mold Mildew Or Moss

Sweeping alone isnt enough to remove mold, moss, or cement from other organic matter. To clean mold stains on your cement, you have to kill the spores or plant material causing the problem.

  • Spray the moss stain on your cement with equal parts of distilled white vinegar and hot water.
  • Using the push broom, scrub the area well after spraying.
  • Rinse with a bucket of fresh water and let the area completely dry.
  • For really stubborn mold or mildew stains on cement, use a solution of 1/4 cup oxygenated bleach mixed into 1 gallon of hot water. Let this sit in place for 15-30 minutes, then rinse and dry the surface.

    Check Scrub And Rinse

    Sweep up the kitty litter and inspect the stained area. If it remains, repeat step one. If the stain is nearly gone, spray the area with a commercial degreaser and scrub the stain with a nylon-bristled brush. Rinse with a garden hose and allow to dry. Repeat if needed.

        How To Clean Concrete Driveway

        You may wonder, What can I use to clean my concrete driveway? Just like concrete patios, you can use a homemade bleach or vinegar solution. You can also use a mixture of water and trisodium phosphate, though it is more harmful to the environment. Other than that, you can use muriatic acid to clean concrete, but it is highly toxic. As such, when using muriatic acid, make sure to wear the proper protective gear.

        Here are the steps you should take when cleaning concrete driveways:

        • Sweep away any loose dirt, dust, and debris.
        • Apply a commercial or homemade concrete cleaner to the surface and scrub using a stiff nylon brush.

        Be careful with the concrete cleaning products you use as some cannot come into contact with paint, and you also want to make sure that run-off does not go into your garden. Some chemicals can be harmful, especially to animals and children, so maybe a natural cleaning solution is best. A conventional concrete cleaner that used to be favored is trisodium phosphate, which has a very strong base and can cause skin burns, blisters, coughing, sore throat, and burning red eyes.

        Similarly, chlorine bleach irritates mucous membranes, can cause eye and skin irritations and is hard on the lungs. Hydrochloric acid is probably the most common chemical for cleaning concrete. However, it is corrosive to the skin, eyes, and mucous membranes. That being said, you can get your concrete clean with a variety of environmentally friendly, homemade products without the use of harsh chemicals and hired equipment such as a power washer.

        Try revisiting the area in a week or two to keep on top of the mold and mildew. Persistence will pay offif you regularly do a light cleaning of the space, more thorough cleanings every few months won’t be necessary.
