Tools and materials

  • 32 oz white vinegar
  • Dish soap
  • 1/4 cup salt
  • A squirt bottle
  • A funnel
Measuring the vinegar

Step 1: Measure the vinegar

Measure out 32 oz (1 quart) of white vinegar. Using a funnel, pour the measured vinegar into a spray bottle. White vinegar is an excellent natural herbicide due to its high acidity. It can effectively kill weeds without harming the environment.

Adding dish soap

Step 2: Add dish soap

Add a small dash of dish soap to the vinegar. Dish soap acts as a surfactant, helping the solution stick to the leaves of the weeds. It also breaks down the waxy surface of the weeds, making the solution more effective.

Adding salt

Step 3: Add salt

Measure out 1/4 cup of salt. Salt is a desiccant, which means it can draw moisture from the weeds, ultimately causing them to dry out and die. Add the salt to the spray bottle with the vinegar and dish soap.

Mixing the solution

Step 4: Mix the solution

Shake the bottle with vinegar, dish soap, and salt. Make sure the salt is dissolved in the solution.

Applying the weed-killer

Step 5: Apply the weed-killer

Hold the squirt bottle a few inches away from the weeds and generously spray the solution onto the leaves and stems. Make sure you cover the weeds thoroughly. You'll start to notice results within a few hours. In many cases, the weeds will start wilting and showing signs of damage within six hours.

    I saw this previously & was so excited to try something that wouldn't be harmful to humans or our dog. Unfortunately it did not work. As another reader stated, some of the tops of the weeds died, but the roots were still alive & the weeds re-appeared quickly. I heard there is a special vinegar for $30 at Lowes. Maybe it would work??

      I also tried it and the tops of the weeds were desiccated but not killed. It works by dehydrating the plant but the roots are still alive.

    The best trick I've found so far is to boil a kettle of plain water and pour over the weeds directly. It takes a few kettle fulls, but so far it's been the most effective after previously trying the vinegar and soap solution. (never added salt before however I'm sure that would boost the effectiveness) Either way, these only work if there aren't other plants nearby that would suffer from the solution for example, walkways, and mulch beds where you have no other items you want to survive.

      Whenever I make spaghetti and add salt to the boiling water, I pour that along the cracks in my sidewalk afterwards.
