Does Baking Soda & Vinegar Work for a Clogged Sink?

I should have taken pictures while I was doing this, but I was just fixing a clogged sink and didn't realize at the time it could be a post. Haha. :) I remembered I had read an article that baking soda and vinegar was a cheap way to clean out a clogged sink. So when I had a clogged sink, I Googled it.

One of the best articles I found about this was actually on the Liquid Plumr website, which seems kind of funny because they are telling you about a household remedy, which if it works, means that you might not buy their product.


However, I actually bought Baking Soda, Vinegar and Liquid Plumr and needed to use a combination of these to unclog the sink, so I guess it didn't matter. And it shows how much they trust their product that they are offering another option.

I liked the article on the Liquid Plumr site because they gave a lot of information behind the science of why baking soda + vinegar works -- for weaker clogs (which I put as an addendum to the bottom of the post). I didn't take pictures, but I did do a recreation in a pot to show how cool the chemical reaction looks when baking soda and vinegar come together.

I am actually pretty good about not putting things down the sink, but maybe I poured a little too much oil down there when I was cleaning up pans and that was clogging the sink. Anyways, it was not draining.

These are the steps you use (from the Liquid Plumr website):

1.) Start by pouring a pot of boiling water down the drain.

2.) Then pour a cup of baking soda and an equal solution of vinegar and water (1 cup water, 1 cup vinegar).

3.) Cover with the drain plug and wait 5–10 minutes.

4.) Flush the drain with boiling water.

Here is a video of what happens when baking soda and vinegar come together. Cool! I think it may help clean pots anyways, so I left it in there. Haha. :)

RESULT: Success! :)

We are good at this! I fixed the clogged sink! It was a little touch-and-go there while I was working on it, but it all worked out. :)

I did find that the household remedy (baking soda+vinegar/water) worked a little bit. I did 2 rounds of this baking soda+vinegar/water remedy.

But what really worked and unclogged the sink was when I poured the the Liquid Plumr in.

I agree with what's on the Liquid Plumr website, baking soda+vinegar/water may work a little bit for weaker clogs, but you need something stronger when the sink is really clogged up.

Give it a try! We are good at this!


Addendum: Science behind Baking Soda + Vinegar/Water in Helping Clogged Sinks

(from the Liquid Plumr website)


Baking soda is sodium bicarbonate, a base. Vinegar is made up of water and acetic acid, which is, you guessed it, an acid.

When you combine these, a reaction happens where molecules get exchanged, creating carbon dioxide and water that bubbles through the clog, breaking it up and moving the looser material.


All drains use gravity to draw the water away, but drainage pipes aren’t pressurized like your water system is. Using boiling water to flush the drain, pressure is added. Along with gravity, this pressure helps remove unwanted goop out of the pipes.


As a side benefit, the carbon dioxide created lowers the water’s pH, making it a relatively weak acid. With time it may work on weaker clogs,
