How to Clean a Drain With Baking Soda & Vinegar


A clean drain that's free of grime and clogs helps you reduce odors in your kitchen or bathroom. Commercial products can be toxic and create strong fumes. Clean your drain with baking soda and vinegar for a more natural and nontoxic cleaning method. Not only will your room be free of odors coming from the drain, your drain will be clean and free of clogs.

Things You'll Need

  • Measuring cups
  • Baking soda
  • White vinegar
  • Large pot
  • Pour 1/2 cup baking soda into your drain. Allow the baking soda to sit for about five minutes as it deodorizes your drain.

  • Pour 1/2 cup white vinegar down the drain. The baking soda and white vinegar will react chemically, causing foam. This reaction is normal and perfectly safe. Allow the foaming combination to sit in your drain for 15 minutes. Any clogs present dissolve under the solution as it works to clean your drain.

  • Bring water to boil in a large pot.

  • Pour the boiling water into the drain, slowly to avoid splashing any on yourself. This water flushes the baking soda and vinegar down the drain as well as any dirt, grime, clogs and odor.

Tips & Warnings

  • Slice fresh lemons into quarters, and run them through your garbage disposal to freshen and clean that part of your sink.
  • Do not pour vinegar down your drain if you've recently used a commercial drain unclogging product. The two will react adversely, resulting in noxious fumes. Wait a few days, and then use the vinegar.
  • Use this method only with metal plumbing, as plastic pipes can melt under the extreme temperatures of too much boiling water.
