Common Causes of Blocked Drains

Soap scum is another common cause. As soap scum combines with loose hair inside your drain, it easily forms a clog that causes many problems.

Different Methods for Cleaning a Smelly Bathroom Sink Drain

When your bathroom sink drain smells bad, you know a problem lurks within the pipes. You need to know several ways to get rid of smelly drains in the bathroom. Even if no one taught you how to clean a bathroom sink drain, you could remedy small clogs yourself.

Salt, Vinegar, and Baking Soda

This classic combination is great for cleaning your bathroom sink drain. First, pour in a cup of salt and let it stay in the pipes for ten minutes. Next, add a cup of baking soda and a healthy pour of white vinegar.

Keep your bare skin out of the way as the baking soda combines with the vinegar. The resulting chemical reaction should be strong enough to remove smelly clogs.

Hot Water and Liquid Dish Detergent

If all you have on hand is your everyday dishwashing liquid, that’s fine. Bring a pot of water to a boil and squirt some dish soap down the drain. Pour the boiling water down your clogged drain.

If the clog is small, hot water and dish soap might be enough to clean a smelly bathroom sink drain, so it’s worth giving this method a try in the absence of other options.


A plunger can also clear your drain, assuming you have the right type for a sink. Fill the sink partially with water and carefully start plunging the sink. When the water level lowers, you know the clog is starting to move. When you are finished, pour hot water down the drain to remove the last of the clog.

Drain Cleaning Products

Chemical cleaners are a good option if you don’t know how to clean a bathroom sink drain that smells. They can help clear away small clogs, but the clog will quickly return if you have a big plumbing problem. Chemicals are often the last attempt before calling a professional for drain cleaning service.

Along with chemicals, a drain snake can remove clogs deep within your plumbing system.
