This is why property owners are always looking for patio cleaners and other ways to remove moss from the patio.

4 Steps to Get Rid of Moss Using Baking Soda

Some herbicides can be used to remove moss from the patio, but chemical treatments like these aren’t usually the first choice for many property owners. A more eco-friendly way of how to get rid of moss on a concrete patio is by using a regular household product: baking soda. To use baking soda to remove moss from the patio, follow the steps below.

1. Collect Your Cleaning Materials

You probably already have most of the supplies and materials required in this moss removal method at home. If not, then a short trip to the grocery and hardware store may be in order. In any case, here are the things you’ll need:

  • Baking soda
  • Water
  • Hand-held sprayer or lawn sprayer
  • Small bucket or container
  • Trowel
  • Hard-bristle brush

2. Prepare the Solution and Transfer to Sprayer

Put one quart of water in a small bucket or container, then add two to three tablespoons of baking soda. Mix the solution until the baking soda is completely dissolved. Add water and baking soda accordingly if you need more.

When the solution is mixed thoroughly, transfer it to a hand-held spray bottle or a lawn sprayer if you need to spray a larger area.

3. Spray the Solution to Moss

Check that the weather is conducive for spray application. Ideally, the weather should be warm and sunny. There should also be no strong winds present, otherwise, it will blow and scatter the mist coming from the sprayer into the air.

When applying the baking soda solution, make sure that the moss is completely soaked through. Avoid getting the solution into your lawn grass or other plants near your patio to prevent them from drying.

After the application, you should immediately see the moss starting to turn yellow. If it doesn’t let the solution sit for at least 15 minutes before checking again. If the moss still looks green and healthy, apply a second round of baking soda solution.

4. Remove the Dead Moss

Once the moss had turned brown and looks dry, you can start to scrape them off the concrete patio using a trowel. Afterward, give the affected area a good scrubbing using a hard-bristle brush to ensure that you get any remaining roots out.

How to Get Rid of Moss Using Bleach

If you want something stronger than the baking soda solution outlined above, you can use a bleach solution instead. The steps to remove moss from the patio using bleach are as follows.

1. Gather Your Supplies

For this method of how to get rid of moss on a concrete patio, you’re going to need the following:

  • Bleach concentrate
  • Water
  • Small container or bucket
  • Hand-held sprayer or lawn sprayer
  • Rubber gloves

2. Dilute the Bleach

It is important to dilute the bleach concentrate with water; otherwise, the solution will be too strong and leave your patio discolored and unsightly.

To dilute the bleach, mix one part of water with one part of the bleach in a small container or bucket. Stir the solution to mix the water and bleach well. Remember to put on a pair of rubber gloves to avoid burning your hands when handling bleach concentrate.

After diluting the bleach, transfer the solution into a small hand-held sprayer or lawn sprayer.

3. Apply the Solution

Again, you’ll want to do the application on windless days to prevent the solution from being blown around by the wind. Remember, bleach can still have a strong effect even when diluted with water, and it can cause patches of discoloration on your outdoor patio furniture, patio umbrella, and plants. It will be difficult to clean your patio furniture when this happens.

Spray the bleach solution directly on the moss, making sure that the moss is completely soaked with the solution. Then, let the solution sit for at least 15 minutes.

4. Rinse the Area

After 15 minutes, rinse the sprayed area with warm water. This will remove the remnants of the bleach, while at the same time helping to loosen the roots of the moss.

5. Remove the Dead Moss

Once the moss has turned brown and dry, you can scrape them off using a trowel. Scrub the area as well to remove get rid of any moss that you weren’t able to remove with the trowel.

6. Rinse with Clean Water

After scrubbing your patio, rinse it again with clean water to remove what’s left of the moss and bleach that may remain.
