How to clean a bathroom sink drain

1. Use hot water

A great way to clear a clogged drain, especially an aluminum sink drain, is to use hot water.

If you are worried about how it may affect your pipes, try pouring in warm water first, allowing it to sit for several minutes, then repeating the process with hot water.

The trick here is to let the hot water sink into clogs in your drain for several minutes before using it. Make sure to pour in at least one pot of water — enough to fill most of the sink.

The reason behind this trick is that aluminum can easily hit the air as opposed to iron and steel, as such, the warm water will create a vacuum effect, flushing out any grime or other unwanted debris.

Never use this method on plastic sinks or drains, as you could potentially melt them.

2. Plunger

Cleaning bathroom sink drains can be very annoying, but it’s actually very easy to fix them. It doesn’t use any chemicals or cleansers that might be harsh, or harmful in any way. Simply put, you should use a plunger to unclog a clogged sink.

The first thing to do is to apply the bathroom cleaner gel to the rubber part of the plunger. The second thing you should do is to fill the sink with water, but do not let it stagnate. Finally, use the plunger and push it up and down for several seconds until you hear a gurgling noise.

Use the plunger and push the dirt around until the water overflows, then carry it away. Now you have repeated this method until all of the dirt has been removed from your sink!

3. Combination of baking soda and vinegar

Baking soda and vinegar is a classic household cleaning combination. They are cheap, effective, and environmentally friendly.

Baking soda can clean up stains on your white clothes, deodorize your fridge, and reduce foot odor (weird but true), meanwhile, vinegar is great for removing soap scum in your bathroom or stripping paint on furniture.

This combination acts as you would expect, baking soda acts as the abrasive, while the vinegar cuts through the stuck-on grime in your sink.

Prepare the baking soda, then sprinkle it over the sink drain. Heat one cup of vinegar in the microwave for two minutes (You can also use an electric kettle).

Once the vinegar is hot, remove the vinegar from the microwave and pour the heated vinegar down the sink drain. This vinegar will cause an immediate reaction with the baking soda and clean your sink.

4. Lemon

Lemon can be used to clean any hard surfaces, including the bathroom sink drain.

It works by getting rid of food debris and smaller dirt particles that are hiding in the drain. Simply take a fresh lemon, remove its peel, and rub it over the entire surface of the drain. Rub until the juice is distributed evenly over the entire surface.

Leave it for a few minutes then rinse with clean water.

You can also do this to prevent soap scum build-up around the drain.  It will cut grease and grease buildup in your pipes, fight off bacteria, and make anything that comes out of your kitchen sink smell better!

5. Salt and baking soda

Salt and baking soda can be used to clean bathroom sink drains.

Mix a few pinches of salt and baking soda with equal measurements. Pour the mixture into your drain and then pour boiling water over it. Leave the mixture in the drain for 15 minutes.

Once the reaction starts, cover the top of the drain with a plate or bowl before pouring hot water down it again. The hot water will push all the dirt, grease, and grime out of your sink drain.

6. Dish soap

Dish soap can be used to clean and deodorize your bathroom sink drains.

Not only does this help to prevent nasty smells from developing in your bathroom, but it also helps to keep your drains clean and free of unwanted grease and oil buildup that could cause future clogs and problems down the line.

Simply pour a small amount of the soap on the drain and let it meltdown. Then, rinse with boiling water until the surface is clean. By following this simple process a few times a month, your bathroom will always have clean drains.

7. Flush with soft drinks

It might be surprising, but refreshing soft drinks like Coca-Cola or Pepsi are great for removing the dirt in the drain pipe.

The sugary content of soft drinks like these is actually excellent for removing stubborn stains. A glass of Coca-Cola, for example, can be used to effectively remove the dirt in your kitchen sink, because it’s particularly good at neutralizing acid.

The idea is extremely simple. Just pour two liters of coca-cola or Pepsi into the kitchen sink’s drain, wait for most of it to go down, wait for 1 or 2 hours for the bubbles to loosen the blockage, then rinse with hot water.

8. Bleach

You can use bleach to clean the bathroom sink drain. Bleach is a mixture of cleansing chemicals, most notably sodium hypochlorite, a strong oxidizing agent that kills bacteria and other microorganisms by releasing oxygen.

To apply this solution, you should pour 200 ml of bleach into it. You should let it sit for 10 minutes, and then rinse the sink by adding a small amount of water periodically until the sink is clean and there is no smell of bleach.

Whenever working with bleach, it is important to not get it in your eyes or mouth and to wear gloves and protective gear around your hand.

9. Chemical cleaner

If you want to clean a bathroom sink drain, using a chemical cleaner can help you fix the problem. Be aware when you use the cleaner because when applying it, you should proceed to read the instruction from the label.

When using chemical cleaner usually apply a drop of its liquid into the clogged gutter and then let it settle for 5 to 10 minutes before washing it away with hot water. This chemical is sticky that’s why you have to be careful when applying it in your sink.

10. Call a professional cleaner

It’s not fun to clean the bathroom sink drain, especially if you have to deep-clean. You might even be overwhelmed with how much work it is to scrub everything down.
