It's simple - vinegar and baking soda.

You know what happens when you put vinegar and baking soda together, right?

It is the same thing you have shown to your kids, or that they have done on their own in the classic science experiment of making a volcano.

When you put the vinegar and the baking soda together it creates a foaming, bubbly reaction which "explodes" like a volcano.

The same idea applies with your drains.

If your drain is running slowly it is most likely because a clog is in the process of building up.

The vinegar and baking soda's bubbling reaction mechanically loosens and removes the clog. It is the perfect natural drain cleaner.


Do not use this method if you have already poured a commercial drain cleaner down your clogged drain.

Most commercial drain cleaners contains chemicals that, when mixed with vinegar, can cause noxious fumes.

Instructions For Making And Using Baking Soda Drain Cleaner


  • 1 cup baking soda
  • 1 cup white vinegar
  • 1 gallon boiling water


1. Pour 1 cup of baking soda down the drain.

2. Slowly pour 1 cup of vinegar down the drain. (If you pour too quickly you will merely flush all the baking soda and vinegar down the drain, instead of allowing it to make the chemical reaction around the clog that you desire.)

3. Let this mixture sit and bubble for approximately 5 minutes.

4. Slowly pour 1 gallon of boiling water down the drain.

The purpose of the boiling water is to completely flush out the clogged drain, after the baking soda and vinegar do their job of loosening the blockage.

If this does not work the first time you may need to repeat the process.

Of course, if you need to repeat again you may also want to add the step of using a plunger on the drain after you pour in the baking soda and vinegar, but before pouring more boiling water down the drain.

This method of using baking soda and vinegar in your drain is best for unclogging a slow drain, not a drain which is completely blocked and which has standing water.
