Ingredients

  • 1 gallon white vinegar
  • 1/4 cup dish soap
  • 2 cups Epsom salt or regular salt

Instructions

  • Pour salt into your container.
  • Add the vinegar.
  • Shake the salt and vinegar together. (It is best to let it sit for an hour or so, to let the salt completely dissolve.)
  • Add the dish soap.
  • Shake again until all the ingredients are combined.
  • Pour into a spray bottle.

Notes

It may take up to 24 hours to see the weeds completely die. Bigger weeds may need multiple treatments.
This spray is best for gravel areas, walkways, etc. Avoid using in flower beds, herb and vegetable gardens, and other areas with plants you want to protect, because the spray will kill the plants as well as the weeds.
For best results, use the spray on a sunny day. The sun will help to dry out the weeds, while a damp or rainy day will make the spray less effective.
