How to Clean Bathroom Sink Drain? What Are the 10 Best Methods To Clean The Bathroom Sink Drain?

Bathrooms are the most vulnerable points in our homes where it is highly prone for bacteria, mold, and mildew. They love a humid environment which is usually found in bathrooms. Our bathrooms may not be 100% sterile, but they should look clean and fresh, which can inspire us to do our best work every day. Here are some tips that you might want to try on washing your bathroom sink drain naturally using common household ingredients.

The most common causes of blocked drains

There are countless reasons why a bathroom sink drain becomes blocked. To understand what causes clogged drains, let’s look at these causes:

Fat, oil, and grease: You may need to pour a liquid fat or oil down the drain. In particular, the idea of running them down the drain with hot water might seem okay. Fats and oils solidify and block pipes once they are flushed down the drain.

Hair: It is often to blame for clogged bathroom sink drains. You can accumulate strands when you comb, wash, or shave your hair over time, which can block your drains or slow them down.

Cosmetics Residues: The bathroom sink should not be used to wash down powdery cosmetics such as foundation, blush, and blush sticks. This can cause blockages in your drain over time.

Soap scum: Bar soaps, in particular, leave a thin film in your pipes. This scum can build up over months or weeks, stopping the flow of water. Changing to liquid soap can help you prevent this issue.   

Top 10 methods about how to clean bathroom sink drain?

1. Use bleach powder or solution

These products effectively kill germs, especially if you have extra dirty sinks with toothpaste stains left, plus food debris stuck on the sides of the sink. It effectively turns your drains into a smooth state with its powerful solution.

2. Use borax or baking soda

Borax is a natural mineral that many of us use in washing clothes and dishes. It is highly effective in dissolving all organic matter, including food debris, grease, grime, and mildew. Besides, it leaves an antiseptic smell on your sink, which can keep further germs away for some time.

Use borax or baking soda

Baking soda is also good in fighting bacteria, but not the strongest like borax does. This product is perfect if you live in an area with lots of trees because this substance contains seven times more acidity than vinegar.

3. Baking soda + vinegar 

These two products help to fight mold and mildew when used together. You need to create a mixture using these two products and pour it into the drain. Let them sit for about an hour and then rinse with water. However, this method is ineffective if there are foul drains with oil or grease build-up and stains, plus food debris particles stuck on them.

4. Baking soda + salt 

Salt may not be as strong as borax but helps break down grease, grime, and mildew build-up. It also helps to smoothen the cover of your sink so it will look nice and clean afterward.

You can try mixing one cup of baking soda with salt, then adding some water into the mix until you have a reasonable porridge-like substance, then store in an airtight bottle. Use this product when your bathroom sink drain smells like rotten eggs or when you see bubbles coming out from your gutters in the morning and in the evening, too.

5. Add a cup of vinegar to your drain overnight

It can help break down grime and food debris, allowing it to be easily rinsed with water afterward. Alternatively, you can add baking soda into your vinegar solution before pouring it into the drain. You get a two-in-one cleaning agent! This method is perfect for mildew build-up but not practical if severe build-ups are stuck inside your shower/bathtub/sink drain.

6. Cleaning coffee grinds from the sink using salt + oil 

Believe it or not, oil is highly effective in cutting through grease and grime build-up. But, you need to use the right kind of oil – veggie-based cooking oil, for instance. If you have lots of coffee grinds in your sink drain, this method will help to clean it in a breeze.

Just add salt to your cooking oil until it is fully dissolved, then pour it down your drain. Leave them overnight because the mixture needs time to break down all fats, food debris and other tough stains stuck in there.

7. Use baking soda + lemon juice

Try using a cup of each product when washing dirty bathrooms that have toothpaste residue stains on the sides plus blackheads build-ups. The mild acidity level of lemon juice can be a great help in loosening the grime and food debris so they can be washed away with water afterward.

8. Use metal cleaner 

Metal cleaners are non-toxic, biodegradable liquids that kill germs and are safe enough to use even for kids. Its cleansing agent effectively melts grease, grime, and organic matter stuck inside your drain. You don’t need a solid chemical to break down these tough stains because it has a very gentle formula.

Also, you can find metal cleaners anywhere household cleaning supplies are sold, whether online or in grocery stores near you. If you want something effective yet very gentle to use, this product is highly recommended.

9. Use dishwashing soap 

A mild dishwashing liquid combined with a half cup of baking soda is an ideal combo for stubborn grease build-up inside your bathroom sink drain. Make sure to put on some rubber gloves before mixing them, then pour the soap-like substance into your drain. Let it sit for about 15 minutes or more, depending on how dirty your gutters are. You may want to wear a mask because this method releases fumes that can bother the lungs and cause headaches.

10. Use wet/dry vacuum 

This device is very effective but only recommended for major clogs like hair, tissue, and other objects stuck in your sink drain that cannot be flushed away with water. You can find an excellent wet/dry vacuum cleaner at a dollar store near you or buy one online, especially if you don’t have this equipment at home.

Toilet paper falls apart in water, right? Just flush a wet/dry vacuum cleaner inside your toilet a couple of times to create suction that will pull up all hard-to-remove substances stuck inside the bowl. You can use a plunger afterward or flush with water once more – whatever works best for you.

How do plumbers clean the drains?

A manual drain snake, often called a plumber’s snake or a drain auger is a little instrument used for bodily pushing through clogs. A corkscrew-shaped hook on the device’s terminal end is fed into a blocked drain or toilet.


Regularly cleaning hair, soap, and scum from your bathroom sink drain will prevent significant mishaps. Add this to-do to your cleaning schedule, and you can avoid clogs in your gutters.
