Home: How to unclog your sink without chemicals

Your kitchen or bathroom can be as shiny and pretty as you like, but if your sink keeps filling up because the drains are blocked, it’s just gross ..

Grabbing some chemical bomb from the shop is one option to try clean your drains, but if you prefer to give natural solutions a go, try this first:

How to clear a sink naturally instead of pouring buckets of Draino and other chemicals down your drain into the earth ☼


  • 2 cups of vinegar (other uses)

You can use pretty much any kind of vinegar except for balsamic 🙂 white vinegar is perfect – I was using apple cider vinegar in the video simply because that was the only vinegar I had available that day.

I boiled 4L / 1 quart of water and that was enough but if you need more or do not have a pot that large, simply boil less, bit by bit.



Use a funnel to fill the baking soda into the drain. If you do not have a funnel, make one with paper, like I did in the video.

Add as much baking soda as possible. Once you cannot get more into the drain, pour vinegar on top.

The mixture might start to fizz and bubble up – if you have a plug, quickly close the drain with it, but if you do not have one, it’s OK too.

Repeat the process until you have used up all the baking soda and vinegar, then cover the drain with the plug if you have one.

Set a timer for 20 minutes.

After 20 minutes, pour hot water down the drain. The water should flow and drain effortlessly.


If the drain is still clogged, repeat the whole process and consider keeping the mixture in your drain longer before following up with hot water.

Another option is to use a plunger or a wire hanger to get things moving.

In case this method does not work, call a plumber and ask for their recommendation rather than just grabbing the next best chemical concoction – it might react with the baking soda and vinegar and do more harm than good.
