You Can Deodorize Your Sink Using The Following Procedure:

Use Baking Soda to Absorb the Smell

Turn the hot water tap into the hottest water setting and let it run for a while. You can as well boil water and flush it down the drain.

When heating water, remove and use it before it boils. The hot water weakens clogs and other debris on the walls of the drain.

Add half cup of course salt. Salt acts as an abrasive for debris stuck on the sides of the drain.

The debris might not be the cause of the smell, but after a while, it breeds bacteria, which emanates the bad odor and can further form clogs.

Do not use table salt due to its fine particles. Course salt has bigger particles efficient in clearing drains.

Remove the drain cover. Sprinkle a half cup of baking soda down the drain.

Pour it bit by bit so as to pour as much baking soda as possible. The baking soda will attach to the areas where the debris and bacteria cling to.

It is best if you warm vinegar or lemon juice to make it more cleaning effective. Add 2 cups of either liquid down the drain.

They react with the baking soda instantly. Cover the drain with a drain cover or a piece of cloth to push the drain’s fizzing mixture down.

Leave the mixture to settle for about 10 min or more. If it has been a while since you last cleaned your drain, let the mixture stay overnight.

Rinsing it too fast will wash away the cleaning compounds before they take effect.

The drain should remain tightly sealed to prevent the gas’s escape, causing pressure and any cleaner left. This blend deodorizes and treats the remaining clogs.

Rinse with hot water to clear the mixture together with the debris and clogs. This ought to clear the bad odor.

For extreme odors, rinse it several times. You can also redo the treatment process using larger amounts of baking soda and vinegar.

Clean the Drain Plugs 

Debris and hair often cling on to the plugs. Remove the plug, check the base for any remaining clogs, and flush it with water and wipe it with a paper towel.

Sprinkle some baking soda or another excellent cleaner to eliminate any odor.

Pour some white vinegar on the drain plug to expel the hidden clogs. Another alternative is to warm the vinegar until it starts to bubble and then dip the drain plug and leave it for some time.

Wash the drain plug at least once every month. This prevents clog build-up. Clogs from hair and grease may cause bad odor on the plug and the whole drain system.

Use an Auger or a Drain Stick

Use an auger or a drain stick to pick up the clogs stuck in the drains. Clogs are the leading cause of the bad odor, or they can also be a breeding ground for bacteria, which can cause a bad smell.

You can also improvise your own drain stick with a metal cloth hanger, although for effective results, it is advisable to use an auger.

Rotate the auger inside the drain to break down debris on the drain walls.

You should flush hot water down the drain to remove any clogs. Avoid hot boiling water, unless you are using a metallic drainpipe since it can damage PVC drain pipes.

If the water flows down the drain smoothly, it is clear of the clog, but if not, use the auger once more or dismantle the pipes.

Clean the P-Trap

If there is still smell emanating from the drain, check the sink P-trap. It is an S-formed material joining the wall outlet and the sink’s tailpipe.

It has two nuts that appear as plastic or metallic, connecting it to other pipes. Loosen the P- trap by turning it in a clockwise direction, and remove it off the pipes.

If your sink structure is in a way that the P- trap is out of reach, you can use other methods to clean it or call a plumber to fix it.

To clean the P-trap, wrap the paper towel on the brush. Push it through the P-trap to eliminate any dunk causing bad odor.

The paper towel removes the grime attached to the walls.

Check the connecting pipes, which may also contain foul-smelling gunk. Using an auger, break down clogs and a paper towel to wipe off the debris.

Return the P-trap to its position. Pour hydrogen peroxide down the drain to clear the remaining debris causing the odor.

Baking Soda and lemon juice can act as a substitute, giving the drain a fresh scent.
