Things You'll Need:
- Bleach
- Water
- Pressure Washer
-
Step 1
I would recommend renting a pressure washer (if you don't already have one). Most rental places have them, or maybe borrow one from a friend.
-
Step 2
Mix water and bleach (4 parts water to 1 part bleach).
-
Step 3
Spray the concrete with this mixture and it should take care of the problem with the moss.
-
Step 4
If you still have problems, try Saferbrand.com. They have a product called Safer Brand Moss and Algae Killer. You can also find these products at Woodstream (www.woodstream.com). This product might also be found at your local garden centers or hardware stores.
