How Does One Mix Bleach or Vinegar With Water to Kill Weeds?

Making a homemade weed killer with bleach requires combining some common household products with water. You need a large pot, a wooden spoon, water, salt, liquid dish soap, a spray bottle, a bucket, rubber gloves and bleach to make this herbicide. You should be finished with this project in about 15 to 20 minutes.

  1. Fill a large pot with water

    Add salt to the water, and bring the water to a boil. Use 1 cup of salt for every 2 cups of water. The salt is important because it kills weeds and leaves the area unsuitable for future plant life.

  2. Add liquid dish soap

    Let the water cool after boiling, then add 1 tablespoon of dish soap for every gallon of water. The dish soap makes the weed-killing solution much stickier, so it will stay on the plants.

  3. Add bleach

    Pour the mixture into a large bucket, and put on rubber gloves. Add the bleach to the mixture. There is no limit to the amount of bleach you can add - the more bleach, the faster the weeds will die. Be careful not to spill the mixture on your clothes or skin when adding the bleach. Stir the mixture with a wooden spoon.

  4. Pour the solution into a spray bottle

    Once the solution is inside the bottle, you can use it to kill weeds. For the best results, spray on a warm, dry day with little wind.
