How to remove moss from your driveway
Moss doesn’t just ruin the overall appeal of your surface.
Still, it also endangers the people around you due to its slippery nature but worry not, since getting rid of moss on your driveway can be easy, depending on the method you will use.
Below you will find several ways to choose from:
Boiling Water Method
Tools: deck brush, kettle
This method might be the cheapest and most basic way to eliminate moss. Directly pour boiling water on the affected area, and ensure the nearby grass or plants are protected from the splash.
After that, wait until the moss has turned yellow, and then you can scrub. However, note that this doesn’t contain any chemicals so the results may vary; you may need to repeat the process for tougher moss problems.
We also do not recommend this for larger projects; going back and forth to boil water will be a hassle.
Baking Soda Method
Tools: Baking soda, bucket, spray bottle, brush, or pressure washer
The baking soda method works best in dry, sunny weather, and you can use it by creating a solution or as is.
For the solution, dilute 10 tablespoons of baking soda in 1 liter of warm water. Transfer it to a spray bottle, then spritz it on the affected areas. Ensure you shake the bottle repeatedly to keep the solution homogeneous.
Let the solution sit for 15 minutes, and then rinse the surface using a pressure washer or scrub the surface using a brush.
For the dry method, generously pour baking soda on the moss and let it sit for 24 hours. After that, utilize a stiff bristled broom to brush the moss.
Baking soda is milder than a bleach solution, but it can still dry out nearby plants and grass, so ensure you take care and cover them well.
Bleach Solution Method
Tools: Bucket, bleach, water, garden sprayer, Brush
As you all know, bleach is a strong chemical that can stain your driveway, so use it properly by mixing it with water. It is important to dilute the bleach, as too high a concentration can be toxic and damage some surfaces. On the other hand, too little bleach in your cleaning solution will be less effective.
Simply utilize the 1:9 ratio, which is 1 part bleach mixed with 9 parts water, adjusting it for smaller or larger projects. After stirring the preferred ratio, transfer it to a garden sprayer and spray it on the surface. Let the solution sit for 15 minutes until the moss dries up.
You can rinse the area using a pressure washer or scrub until all the moss has been removed. Also, don’t forget to wear gloves when using bleach to kill moss.
Vinegar Solution Method
Tools: Vinegar, garden spray, rake, or brush
This is another natural method if you don’t want to use harsh chemicals on your surface.
Utilize the 1:1 ratio: one part white vinegar mixed with one part water, then transfer to a garden spray. Spritz generously on the moss and wait for a couple of days until the plant has dried out.
Repeat the spray solution if the moss is still dry, and then use the stiff-bristle brush to remove the dead moss. Be sure to rinse the surface with a garden hose or pressure washer.
Moss Killer Method
Moss killer products contain iron and naturally occurring iron elements which are very effective at removing moss on your driveway. The chemicals will suck out the moisture from the moss and are toxic to most spores, causing them to dry and eventually die.
Depending on your product, the steps will vary, but it will surely kill the moss on your driveway.
