Tips to Maintain Your Bathroom Sink Drain One of the best things you can do to ensure that your bathroom sink drain stays in tip-top condition is to keep it clean and free of odors. A smelly and gross sink drain can make your whole bathroom smell not very pleasant. The good news is, with easy, regular maintenance, you can keep your sink drain clean and odor-free.
You can begin by pouring some hot water down the drain. This helps to break up any debris or gunk stuck in the drain. You can also use a solution of baking soda and vinegar to aid in cleaning out your drain. Simply flush some baking soda down the drain, then flush a little vinegar down after it, and let the solution sit for a couple of minutes before rinsing into the drain with hot water.
If you notice that your bathroom sink is running slowly or not draining properly, you may have just a few simple steps to unclog your bathroom sink. Here’s an easy one: The plunger. Just position the plunger over the drain and ensure you get a tight seal, then pump the plunger vigorously up and down to release the clog.
You can use the plumbing snake if the plunger doesn't work. This long, snake-like implement can really reach down into the drain to break apart any particularly troublesome clogs. You simply put the snake in the drain and turn it to attach to the clog, then pull it out.

Another good option is a baking soda and vinegar combination, as previously noted. This carbonated mix can help dissolve clogs and get your sink drain clear. Simply throw the baking soda down the drain, followed by the vinegar, and let it sit for some time before rinsing with hot water.

One other way to keep hair out of your drains is to refrain from washing your hair in the sink. Instead, try using a hair catcher in the tub that can trap the loose strands before they start making a mess of your sink down the drain. This easy solution will keep hair from clogging up your sink drain.

If you are having trouble with your bathroom sink drain, here are some of the most common problems you can face and what you can do about them. One of the most common is a clog in the drain, often created by hair, soap scum or hygiene products. To unclog this, there might be a couple of things that you can do, you can plunge it, or use a plumbing snake.
