Dousing the area with boiling water, particularly areas infested with other unwanted growth, is an efficient and cost-effective method of eliminating moss from concrete surfaces. After pouring a generous amount of hot water over the area, scrub the area with a sharp brush and then use a hose to wash away any remaining moss.

Clean exposed concrete slabs without chemicals

Once your exposed concrete slabs are thoroughly moistened, you can next apply a cleaning product. Do not use cleaning products that contain strong chemicals as this can destroy the coating or seal on the concrete. Instead, look for natural cleaning products. Then allow the cleaner to sit on the surface for a specified amount of time before rinsing it off.

  • Soda

It is possible to remove grease stains with soda water. It's really ridiculous, but it's true. This is due to the three essential components of soda – carbonic acid, phosphoric acid and citric acid.

These three acids, when combined, are effective in removing dirt from concrete. This process works equally well with any cola that contains these ingredients. Pour out the cola or soda water and let the liquid sit on the concrete for fifteen to thirty minutes. To remove the rest of the stains, you can use either scrubbers, towels, or a mop in addition to the cleaner and water.

If you are worried about the plants that are nearby while cleaning your patio or walkway, vinegar (or baking soda/baking soda) cleaner is the right solution for you!

Put some dishwashing detergent in a spray bottle and fill the rest of the container with equal parts water and vinegar (or water and baking soda/baking soda). Spray the solution onto your floor tiles and then wait about half an hour. The concrete should then be scrubbed and rinsed.

  • Seifenwasser

If your patio (or walkways) survived the winter in relatively good condition, a soap solution may be enough to complete the cleaning of the patio and return it to its former glory. Make a soap solution by mixing warm water with liquid soap or dishwashing detergent in a bucket. To remove the stains from the patio, use a stiff brush and pour the solution over the entire surface. When you're finished, you can give the surface one final wash with clean water using a garden hose or pressure washer on a low setting (see below for more information).
