How to get rid of moss on concrete
Let’s answer the question of how to clean moss off concrete.
Here are the four methods.
1. Use bleach
Bleach is a potent chemical that discolors the concrete’s surface.
However, it’s a popular technique for moss removal. If you want to use this method, test it on a small area and see if your color is intact.
Here are the steps on how to use bleach to kill moss on concrete:
- Combine 20 ounces of bleach with water based on your bottle size
- Apply the mixture to the surface with a sprayer
- After covering, clean the surface thoroughly
- Once the moss has gone yellow, leave the area for 20 minutes
- Use a pressure washer or plain water to rinse the area
2. Use a moss-killer spray
The finest moss removers, such as Smart Seal Moss Remover, doesn’t include bleach.
It won’t stain or harm your lawn if you’re cleaning a walkway next to your grass, and it can be pressure washed or used as a spray.
Follow these steps:
- Use the moss killer to pressure wash or spray the entire surface
- Allow it to work for at least an hour
- You can use a hose or pressure washer to remove the dead moss
If there are any cracks in the concrete, fill them after cleaning. They can be a perfect spot for moss to regrow.
3. Moss removal from concrete with vinegar
A half-and-half vinegar-water solution can help eradicate difficult stains.
However, the best vinegar is white vinegar, which you can combine in a spray bottle for quick and easy application in large areas.
- To get rid of the moss, try putting full-strength vinegar on it
- Ten minutes are appropriate for the vinegar to sit
- Clean the area with a pressure washer with optimum PSI for concrete
- If required, reapply vinegar to the troubled regions
4. Killing moss on concrete with baking soda
If you want to strengthen the above solution, add baking soda.
Baking soda kills moss, and the job is done faster and better.
Just follow the same steps, and you’ll be good to go.
Quick tips and tricks to save time and money
Here are a few tips and tricks for removing moss off concrete.
- In contrast to spray bottles, applying chemicals with a pressure washer will be simple, quick, and incredibly effective
