How To Use Vinegar And Baking Soda For Drain

Clogged drains can be a frustrating and persistent issue for homeowners, often leading to costly repairs and unpleasant odors. 

However, a powerful and environmentally friendly solution lies in your pantry: vinegar and baking soda. 

The cleaning mixture resulting from the mixture of these two ingredients will help you save money by avoiding expensive chemical products or professional services, and also help protect the environment by using natural, non-toxic ingredients. 

In this article, we will explore the science behind the dynamic duo of baking soda and vinegar and provide a step-by-step guide on how to properly use the solution resulting from their mixture for drain cleaning.

Is it safe to put vinegar and baking soda in the drain?

Using vinegar and baking soda to clean drains is a safe and eco-friendly method. 

The combination of these two natural ingredients does not create harmful chemicals or blockages. 

In fact, the chemical reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) produces carbon dioxide gas and water, both of which are harmless. 

This reaction generates fizzing and bubbling, which helps to break down and dislodge accumulated grease, dirt and grime in your pipes.

While vinegar and baking soda are safe for most household drains, note that it may not be effective for clearing severe blockages or tree root intrusions in your pipes. 

In such cases, it is recommended to seek professional assistance.

downsides to using baking soda and vinegar As opposed to professional solutions or other natural products

Using baking soda and vinegar to unclog a drain can be a safe, affordable and eco-friendly option, but there are some potential downsides compared to using a professional solution or other natural treatments.


Baking soda and vinegar may not be as effective as commercial drain cleaners for severe clogs or those caused by large, solid debris. It works best for mild to moderate clogs caused by grease, soap scum or hair.


This method can take longer to work than using a professional drain cleaner. Multiple applications may be necessary, and you may need to wait for a while between applications.

Incompatibility with other chemicals 

If you’ve recently used a chemical drain cleaner and it hasn’t worked, you should not use baking soda and vinegar. Mixing different types of chemicals can create harmful reactions or fumes.

Limited effect on biofilm

Baking soda and vinegar might not effectively remove the biofilm, a slimy layer of bacteria that can form inside your drain pipes. Commercial drain cleaners or enzymatic drain cleaners might be more effective in dealing with biofilm.

When considering alternative natural treatments such as using a plunger, drain snake or enzymatic cleaner, each has its pros and cons. 

Plungers and drain snakes can be effective for mechanical removal of clogs but might not address the underlying issues of grease and soap buildup. 

Enzymatic cleaners use bacteria and enzymes to break down clogs, but they can take longer to work and might not be as effective on larger, more severe clogs.

At the end of the day, the best approach depends on the nature of the clog, the condition of your pipes, and your preferences for safety and eco-friendliness.

What is the ratio of baking soda to vinegar to clean a drain?

The ratio of baking soda to vinegar for drain cleaning is typically 1:1.

How to use vinegar and baking soda for drain

Using vinegar and baking soda to clean a drain is easy. 

Here’s a step-by-step guide:


  • 1/2 cup of baking soda
  • 1/2 cup of white vinegar
  • Hot water (optional)


  • Remove any visible debris from the drain opening and ensure that there is no standing water.
  • Pour 1/2 cup of baking soda down the drain. You can use a funnel or spoon to help guide the baking soda into the drain.
  • Slowly pour 1/2 cup of white vinegar into the drain. The vinegar will react with the baking soda, creating a fizzing and bubbling action. This reaction helps break down grease, soap scum and other buildup inside the drain.
  • Cover the drain with a drain stopper or a small plate to keep the reaction contained within the pipe.
  • Allow the baking soda and vinegar mixture to sit in the drain for at least 15 minutes. For tougher clogs, you can let it sit for up to an hour.
  • After the waiting period, remove the cover and flush the drain with hot water for a few minutes to help wash away the loosened debris. Be cautious when using hot water if you have PVC pipes, as extremely hot water can damage them.

Tips for success:

  • For a more effective clean, try heating the vinegar before pouring it into the drain.
  • Use this method regularly (e.g., once a month) to help prevent clogs and maintain clean drains.
  • Avoid using chemical drain cleaners before or after using the baking soda and vinegar method, as it may cause harmful reactions.
  • If the clog persists after the first attempt, you can repeat the process a few more times. However, if the issue still remains, consider using a plunger, drain snake or calling a professional plumber.
  • Remember, baking soda and vinegar are best suited for mild to moderate clogs. For more severe clogs or those caused by external factors like tree roots, you may need professional assistance.

What kind of drains can you clean with the solution?

You can use the baking soda and vinegar solution to clean various types of household drains. These include:

  • Kitchen sink drains: Baking soda and vinegar can help break down grease, food particles and soap scum that can accumulate in kitchen sink drains.
  • Bathroom sink drains: This solution can help remove soap scum, toothpaste residue and hair clogs in bathroom sink drains.
  • Bathtub and shower drains: Baking soda and vinegar can help dissolve hair, soap scum and other debris that commonly clog bathtub and shower drains.

Alternatives for vinegar and baking soda for drain

There are several alternatives to using vinegar and baking soda for cleaning drains. Some options include:

  • Plunger: A plunger is a simple and effective tool that can dislodge clogs by creating pressure in the pipes. It works best for minor to moderate clogs in sinks, toilets and bathtubs.
  • Drain snake (auger): A drain snake or auger is a flexible, long tool that can be inserted into the drain to break up or remove clogs. Manual and powered versions are available, and they can be effective for a wide range of clogs.
  • Enzymatic drain cleaner: These cleaners use enzymes and bacteria to break down organic materials in clogs, such as hair, grease and food particles. They’re eco-friendly and relatively safe for pipes, but they can take longer to work than chemical drain cleaners.
  • Chemical drain cleaner: Commercial chemical drain cleaners like Drano or Liquid-Plumr contain strong chemicals that can dissolve clogs quickly. However, they can be harmful to the environment, pose health risks if not used carefully and potentially damage old, corroded or fragile pipes.
  • Hot water and dish soap: For minor grease clogs in the kitchen sink, pouring hot water mixed with a few squirts of dish soap can help dissolve the grease and flush it away.
  • Salt and hot water: Pouring a mixture of salt and hot water down the drain can help break up minor clogs and remove debris.
  • Professional plumbing services: If you have a severe or persistent clog, it’s best to call a professional plumber who can use specialized tools and techniques to address the problem.

How often should you clean your drain?

The frequency of cleaning your drains depends on usage and the specific drain type. 

In general, it’s a good idea to clean and maintain your drains regularly to prevent buildup and clogs. 

Here are some recommendations:

  • Kitchen sink drains: Clean them once a month or as needed. Grease, food particles and soap scum can accumulate quickly in kitchen sinks, so regular cleaning can help prevent clogs.
  • Bathroom sink, bathtub and shower drains: Clean them every 1-3 months or as needed. Hair, soap scum and other debris can cause clogs in these drains.
  • Laundry/utility sink drains: Clean them every 3-6 months or as needed. Lint, detergent buildup, and other debris can accumulate in these drains over time.

When using vinegar and baking soda for drain cleaning, follow the same frequency guidelines. 

Regularly cleaning your drains with this method can help prevent clogs and maintain their functionality.
