Moss appears as dense, green patches and mars the aesthetics of your home. But, how to remove moss from driveway? It is a challenge!
Moss and mold may appear similar and do make their appearance in areas with high moisture levels and limited sunlight. However, they are different.
However, it’s important to recognize that moss is a non-vascular plant, while mold is a type of fungus. While moss is generally harmless and primarily a cosmetic issue, mold can pose health risks and requires proper remediation to address.
How to Remove Moss from Driveway without Chemicals?
It is a good idea to attempt to remove moss from a driveway without using any harsh chemicals to begin with.
1. Garden Hose & Scrub
For small patches of moss growth you can use your garden hose a scrubber and some elbow grease. Begin by scrubbing the moss to loosen it away from the concrete or asphalt driveway.
Next, wet the moss patch and scrub again. This is an iterative process of scrubbing and washing away the moss with the garden hose.
I recommend using SCRUBIT Moss & Weed Remover Wired Grout Cleaner Brush.
It has small tapered wired grout cleaners, uniquely designed for moss removal from all types of hard surfaces.
With some effort you will be able to clear the moss patch. However, keep an eye on the spot. Should the moss patch return after a few days, it means that the moss has taken roots. This will require use of a chemical treatment to kill the moss from its roots.
2. Pressure Wash
Using a pressure washer is an efficient way to remove moss from concrete surfaces. In my opinion it works best when moss growth is widespread but you detect it early on; that is before it has had time to get ingrained in the concrete.
When using a pressure washer to remove moss from your driveway, ensure correct pressure and technique. Attach the appropriate nozzle tip for a fan-like spray pattern to prevent concrete erosion.
Begin at the highest point, working down with overlapping passes. Maintain a distance of 12 to 18 inches from the surface and angle the nozzle downward to prevent water from loosening the concrete.
Better still, use a pressure washer surface cleaner.

How to Remove Moss from Driveway Using Household Products?
More often than not, moss has taken roots in your driveway. At this point you have no option to kill it either with household products or commercial products. Here are some household products that work.
3. Bleach and Pressure Wash
In case the moss growth is widespread and has had some time to become ingrained into the surface of the concrete driveway, then you are better off using a bleach solution before the pressure wash.
Bleach is known for its moss-killing properties. Add around 1 – 1 1/2 lbs of bleach to a bucket of of water to prepare a bleach solution. Fill the solution in a backpack or garden sprayer and spray the moss growth.
Wait and let it sit for about 15 minutes. The bleach will kill the moss from the roots. Then, just use a pressure washer to rinse off the bleach solution and remove the dead moss. Use a scrubber if required.
TIP: Adding liquid detergent to the bleach solution will get you even better results.
4. White Vinegar
White vinegar is a natural disinfectant that can kill moss and prevent their regrowth on concrete surfaces. This method is ideal for small areas.
To use vinegar for moss removal, simply pour undiluted white vinegar into a spray bottle and spray it onto the affected areas. For moss that is widespread but not too old, you could use a vinegar solution with water in a ratio of 1:3 or 1:4.
You may need to do this everyday for a week, in which time the moss should be all dead. Then, scrub the area with a brush and rinse it off with the garden hose.
The advantage of using white vinegar is that it is safe to use and environmentally friendly.
How to Remove Moss from Driveway Using Commercial Products?
For highly widespread and aged moss growth on concrete driveways, commercial moss killers will become necessary. Here are some top options:

Preventing Moss Growth on Concrete Driveways
Preventing moss growth on concrete driveways is essential for maintaining their appearance and structural integrity. Here are some practical tips:
Regular Cleaning: Regularly clean your concrete driveway to remove dirt, debris, and organic matter that can contribute to moss growth. Use a broom, pressure washer, or hose to wash away any buildup.
Proper Drainage: Ensure good drainage around your concrete driveway to prevent water from pooling or accumulating. Poor drainage can create moist conditions ideal for moss growth. Consider installing drainage channels or grading the area away from the driveway.
Sealing: Apply a concrete sealer to your driveway to create a protective barrier against moisture and moss. Sealers can also enhance the appearance of the concrete and make it easier to clean.
Sunlight Exposure: Maximize sunlight exposure to your driveway by trimming trees and shrubs that cast shadows. Sunlight helps inhibit moss growth by drying out the surface and reducing moisture buildup.
Prompt Repairs: Repair any cracks, chips, or damaged areas on your driveway promptly. These damaged areas can trap moisture and provide a conducive environment for moss growth. Use a concrete patching compound to fill in cracks and seal them properly.
