A Guide to Using Baking Soda for Removing Moss From Walls

by

Perhaps you’re not a fan of the rustic look of moss on the walls or maybe you’re concerned that the growth may damage your walls by creating holes and cracks. One thing is certain, you want the moss gone!

Moss growth is a common problem that occurs in damp and shady areas. Walls are porous, absorbing moisture from the air, which, coupled with long periods of shade makes them a good growing spot for moss.

Fortunately, there is a simple and highly effective method for removing moss from walls: baking soda.

How Does Baking Soda Work?

Baking soda is a common household item used for numerous cleaning purposes. As a base, it raises the PH of the moss, stopping the growth and killing it.

Many users have come to appreciate baking soda because it’s easy to apply, it does not harm the walls and the environment, and most importantly, it’s effective.

As earlier mentioned, applying baking soda to remove is easy and does not take much time. 

Here are the steps to follow:

  1. Sprinkle the baking soda on the mossy walls, ensuring it’s fully covered
  2. Let it sit for at least 24 hours or longer for thicker moss growth
  3. When the moss turns brown, scrape it off with a brush 
  4. Pressure wash the walls to rinse away any residue
