When your bathroom sink has water standing in it, it almost always means you have a clog or restricted flow somewhere in the drain system. The water is unable to escape as fast as it is being poured or produced, indicating a blockage that requires clearing.
Unclog a Sink With Vinegar and Baking Soda
If your bathroom sink won't drain but there is no obvious blockage, the issue usually stems from a blocked air vent, a dirty sink stopper, or a buildup of soap scum. These steps will help you resolve the issue.
In most cases, a clogged drain will not fix itself. While minor accumulations of soap scum may occasionally wash away with continuous water flow, most blockages—such as trapped food, hair, or grease—will simply get worse and completely block the pipe without manual intervention.
One of the most common reasons there's water backing up in your kitchen sink is a clogged pipe. Over time, grease, food particles, soap scum, and other debris build up inside your sink drain, making it harder for water to flow freely. A clog in your kitchen sink drain doesn't always happen overnight.
Unclog a sink quickly by pouring boiling water and dish soap down the drain to melt grease. Follow up with a natural mixture of 1 cup baking soda and 1 cup white vinegar. Let it foam for 15 minutes, then flush it completely with a final pot of boiling water.

This method, ideal for tackling minor blockages, leverages the degreasing power of dish soap combined with the force of hot water to dislodge and dissolve clog-causing residue.
Baking soda and vinegar do not effectively unclog drains. Instead of clearing debris, mixing them chemically neutralizes both ingredients into salt water. The fizzing reaction is visually satisfying but largely escapes upwards, offering zero power to dissolve grease, hair, or stubborn sludge.
If your drain isn't visibly clogged but still won't drain, the issue is likely a blocked plumbing vent, a hidden P-trap restriction, or a faulty pop-up stopper. Check these four common culprits to get your sink moving again.

It's best to instead opt for a Drano alternative as a safer and more plumbing-friendly way to unclog your drains. Some of the best Drano alternatives include using a plunger or pipe snake, soap or salt mixed with boiling water, or baking soda and white vinegar.
