Avoid the disruption of a clogged sink, tub, or shower drain with an eco-friendly DIY drain cleaner. Safer and less expensive than chemical cleaners, this simple solution is made from a few basic pantry items. A homemade drain cleaner may take a few tries to completely clear a really tough clog, but give this DIY solution a try before resorting to caustic and toxic commercial drain cleaners.
What Does Homemade Drain Cleaner Do?
You don't always need the strength of a chemical drain cleaner. A slow drain often can be cleared with a homemade drain cleaner concoction consisting of boiling water and a mixture of baking soda and white vinegar. Baking soda (a base substance called sodium bicarbonate) and vinegar (a mild acetic acid) react together to create a fizzy, bubbly action that releases carbon dioxide, which can loosen up clogs so they can be washed down the drain. Chase the mixture with boiling water, which helps to wash out any clogs or debris, and you've got a reliable recipe for fighting clogs.
Follow these specific steps to make a DIY drain cleaner that will unclog your sink, tub, or shower drain.
Safe Homemade Drain Cleaner Recipe
Equipment / Tools
- Drain stopper
- Boiling water
- 1/2 cup Baking soda
- 1/2 cup White distilled vinegar
Clear Any Standing Water
If your sink (or tub or shower) is full of backed-up water, bail out as much of the water as you can by using a cup and dumping the water into a bucket. It's fine to leave a small amount of water down in the drain opening itself, but the sink, shower, or tub should be mostly empty so your drain cleaner can get as close as possible to the clog.
Pour in Boiling Water
If you're working on a sink or tub drain, first remove the sink pop-up stopper or the tub stopper to gain better access to the drain. Pour a small pot full of boiling water into the drain.
Be cautious while pouring the boiling water, as it may splash or splatter.
Add Baking Soda
Pour 1/2 cup of baking soda into the drain.
Pour 1/2 cup of vinegar into the drain.
Cover the Drain
Cover the drain with a stopper, if available, and let the mixture work for 10 minutes. The baking soda and vinegar will fizz and bubble a lot; covering the drain forces the reaction downward instead of up and out of the drain, but it's not critical that you cover the drain.
Add More Boiling Water
Pour another pot of boiling water into the drain. This will help wash away any clogs that the baking soda and vinegar loosened up.
Clear the Drain
Flush the drain with hot water from the tap to help remove any remaining debris from the drain pipe.
Repeat as Needed
If you notice some improvement after the first attempt, try the drain cleaner again. If the drain is still slow after multiple attempts, you may need to try a more extreme solution.
If this remedy doesn't clear the clog, it's time to consider disassembling the drain trap, if possible, and/or snaking the drain with a drain snake. Place a bucket under the trap before removing it to catch water (and crud). The nice thing about using a homemade drain cleaner is that you don't have to worry about nasty chemicals pouring out along with the water. If no amount or type of drain cleaner works, it may be time to call in a plumber.
