How to Unclog a Kitchen Sink

Using Baking Soda and Vinegar

A baking soda and vinegar mixture is a natural solution for unclogging the kitchen sink. You can use a combination of equal parts of baking soda and vinegar to break down debris and grease that's clogging the sink after leaving it to work for about 15 to 20 minutes. Here's how to unclog a kitchen sink with baking soda and vinegar, step-by-step:

  1. Pour 1 cup of baking soda down the drain first.
  2. Then, pour 1 cup of white vinegar down the drain as well.
  3. Let the two ingredients sit in the sink for 15 to 20 minutes.
  4. Turn on the sink or pour hot water down the drain to clean it and make sure that the clog is gone.

Tips for Maximizing the Effectiveness of this Method

To get the greatest results, there are a few guidelines to remember while using baking soda and vinegar to unclog a kitchen sink:

  • Use hot water to flush the vinegar and baking soda down the drain. It should also help clear up the clog.
  • Let the white vinegar and baking soda sit in the sink for at least 15 minutes and at most 20 minutes.
  • Do not use this method if you have a garbage disposal or septic tank because it may not work on big debris or foreign objects and disturb the septic tank's equilibrium.
  • Use other methods after using the vinegar and baking soda method to clear up clogs.

Using a Plunger

The most typical equipment for clearing a clogged kitchen sink is a plunger. You'll need to place the plunger over the drain and press down firmly to produce suction. Then, slide the plunger up and down several times to remove the clog. You can remove excess water from the sink with a small cup or container beforehand but leave enough to check if the clog has cleared up. Here's how to unclog a kitchen sink with a plunger:

  1. Get a bucket, a small cup or container, and your plunger.
  2. Place the bucket near your kitchen sink to collect any water that spills in the process.
  3. Use a small container or cup to get rid of most standing water in the kitchen sink that can splash around and spill on the floor.
  4. To create suction and to help you check if the kitchen sink has cleared up, leave some water in the sink.
  5. Place the plunger over the kitchen sink drain and press down on it to create suction.
  6. To clear up the clog, raise and lower the plunger until the clog has cleared.

If the plunger method does not work, use our other recommended methods next or call a professional plumber to handle the clog.

Tips for Getting the Best Results With a Plunger

To effectively use the plunger to unclog your kitchen sink, keep the following in mind:

  • Remove as much standing water in the sink as you can beforehand but leave some to generate suction.
  • Use a flange plunger which is designed for sinks with its broad base.
  • Use different plunging methods if one doesn't work for you. Some homeowners have found that swaying the plunger from side to side is more effective than pushing it up and down.
  • Use our other methods first and then use a plunger to unclog the sink.
  • If required, repeat the steps on how to use a plunger again. It could take more than one try to completely remove a clog.

Using a Drain Snake

You can also learn how to unclog a kitchen sink with a drain snake. A drain snake is a thin, flexible cable with a wire spiral or a corkscrew-like end that's used to clear up clogged drains. You just need to remove any standing water in the sink, insert the drain snake, and turn the handle to clear up the obstruction in the drain:

  1. Get a bucket and place it near the sink to catch any water that might spill over while you're unclogging it.
  2. Use a small cup or container to remove any standing water in the sink.
  3. Place the drain snake into the sink and down the drain until you feel the resistance of the obstruction.
  4. Turn the handle counterclockwise after insertion to clear up the obstruction.
  5. Remove the drain snake and let the water run through the drain to check if the clog is gone.

Try to use the vinegar and baking soda method before using a drain snake. If this doesn't work, call your professional plumber.
