How to Use Bleach As a Grass & Weed Killer

If grass and weeds take over and you wish to remove them from your landscape, some household materials serve this purpose effectively and affordably. Standard chlorine bleach mixed with water can be effective for killing unwanted grass and weeds. Choose a time when rain is not in the weather forecast for 24 hours and spray the area generously with diluted bleach.

Fill the measuring cup with 16 ounces of water and pour the water into the spray bottle.

Add 1 ounce chlorine bleach to the water.

Screw the cap of the spray bottle onto the bottle tightly. Shake the diluted bleach vigorously to mix the ingredients.

Spray the diluted bleach onto the foliage and at the base of each plant you wish to kill. To kill grass, thoroughly saturate the entire grassy area you wish to eliminate with the bleach solution.

Reapply the bleach solution after two days if the plants are not completely dead.

Mix Dish Liquid, Salt & Bleach For Weed Killer

Invasive weeds are the bane of any home gardener's existence. Many commercial herbicides may be toxic not only to weeds but to humans and animals as well. Fill a large pot with water and bring it to a boil. Use a ratio of 1 cup of salt for every 2 cups of water. The liquid dish soap acts as a surfactant, which means it helps the solution stick to the plant. Slip on some rubber gloves. The stronger the bleach, the faster it will kill the weed, so add as much as you are comfortable with. Spray the solution on the weeds on a warm, dry day with little or no wind.


Do not spray the bleach solution on your skin or in your eyes. If you spray yourself with the bleach solution, rinse the area generously with cool water to remove the bleach. If you spray a plant or an area you do not wish to kill, rinse the area with a garden hose to dilute and neutralize the bleach.
