  • Gloves for mold and algae Removal
  • Wearing a dust mask and goggles
  • Pressure washing with a sharp push sweeper
  • Bleach or vinegar

Step #1. First, spray the area with a solution of white vinegar and water to eliminate any mold or algae present.

Use a gallon of water and a cup of household bleach, or 5 percent white vinegar. Be careful not to damage the rocks by using a hard-bristled brush or scraper to scrape the extra material between the stones.

Step #2. You can remove mold and algae off hardscapes with a simple pressure wash, but you have a few other options if that doesn’t work. There are a few things to keep in mind while using bleach, including the fact that it has a bigger environmental impact and can even alter the color of some rocks and stones.

Step #3. After using a bleach solution to eliminate mold or algae, you will need to wash the area. Mold and algae stains on hardscapes may necessitate a second and third application of this method.

If you can’t go through all of the rocks in a day, break them up into sections and return the next day to finish the rest. When the task is complete, proceed in the same method.

Step #4. Pouring soil back into the landscaped area and then adding rocks on top is possible if you place all the stones aside to spread out once you complete the task.

The spores will have little trouble finding the resources they need to grow. The dirt that accumulates on top of access to natural pavers, tiles, or slabs quickly decomposes, increasing the risk of mold.

Thorough maintenance with clean water, such as power-scrubbing a patio, is the right approach to prevent mold from forming.


Maintain the rocks clean and dry

Rock surfaces, especially those used indoors, should be maintained dry at all times to preserve the natural stone’s seal. It doesn’t matter if you use the rocks outdoors or indoors.

Good care and preservation of natural stone are relatively simple if we all know how to do it.


Clean with a mixture of water and bleach

You may remove mold with household bleach. Apply the mixture with a synthetic brush or pad made of soft nylon.

To finish cleaning, use clean water and a rock cleaner and sealant after allowing the bleach and water solution to rest for about fifteen minutes after the initial scrape.



Aside from knowing how to remove mold from rocks, you also need to make sure the space can dry out properly and has sufficient airflow to avoid future mold or algae problems. You can prevent water from gathering by pruning hanging trees and shrubs, moving patio furniture, or creating drainage routes.
