Baking soda is being alkaline in nature is known to react vigorously with vinegar which is purely acidic.

For this reason, it is recommended not to combine them for cleaning purposesHowever, in certain cases like cleaning a clogged drain, the combination can work well.

  1. Pour Some Hot Water

If your drain has become inefficient in draining water, it may require some essential cleaning measures. Using hot water is one of the effective ways to make your cleaning easier.

  • Take some hot water in a small bucket or pot. If you have a water heater then it would be easier. Make sure that the water is reasonably hot but not hot enough to burn your skin.
  • Pour the water carefully down the drain. Pour it in such a way that the water touches all the areas inside the drain.
  1. Mix Baking Soda in Water

As noted above on this site, mixing baking soda with vinegar can cause unpleasant reactions. Sometimes, it can even cause a mild explosion. Hence, it is convenient to use it separately

  • After pouring hot water you can start preparing a mixture of baking soda and cold water. Mix half a cup of baking soda in a cup of water.
  • Pour the mixture down the drain just as you had poured the hot water. Wait for 3 to 5 minutes before you proceed further.
  1. Prepare a Vinegar Solution

After pouring baking soda solution down the drain you can start preparing the vinegar solution.

  • Take a pot and add 1 cup of white vinegar and 1 cup of hot water. Hot water can multiply the cleaning effects of vinegar.
  • Pour the mixture down the drain and cover it using a drain plug. The vinegar would react with the particles of baking soda and cause some sputters. However, if you cover the drain with a plug you may not feel the intensity of the reaction.
  1. Wait for 10 Minutes

Whenever you use cleaners on your drains, you should leave the area undisturbed for several minutes. If you open the faucet or pour water immediately, it can considerably reduce the effect of cleaning.

  • After pouring hot vinegar solution, wait for 10 minutes before pouring more water. After that, you can flush the drain using normal water or once again use some hot water.
  • If you feel that the drain has been unclogged and cleared of all the debris you can skip using hot water.
  1. Flush the Drain

As a final step, you may flush the drains with copious amounts of water. This is to clean up all the loosened grime and debris.

  • The baking soda and vinegar treatment may take around 15 to 20 minutes to bring the desired result. Meanwhile, if you feel that the drain requires more cleaning, then you can flush with hot water.
  • You can again sprinkle a handful of baking soda before pouring more water. This would definitely dissolve the leftover grime and make your drain as clean as possible.


  • Before cleaning with baking soda and vinegar people often clean the drain with boiling water instead of hot water. This would intensify the cleaning process. However, you need to be extremely careful while pouring boiling water. Also, you may need precautions like wearing rubber gloves and boots to avoid getting burnt.

Although a blend of baking soda and vinegar is considered to be dangerous, when they are used together in the right manner, the results can be quite great. However, you should always use them separately, one after the other, in order to avoid the risk of an explosive reaction.
