How to Remove Smell From Sink Drain: A Guide to Eliminating Unpleasant Odors

A foul smell emanating from your sink drain can be both irritating and embarrassing. Not only does it make your kitchen or bathroom unpleasant to be in, but it can also indicate a potential plumbing issue. If you’re wondering how to remove smell from sink drain, follow this comprehensive guide to eliminate those odors and restore freshness to your space.

1. Clean the Drain Stopper
Start by removing the drain stopper and cleaning it thoroughly. Over time, debris and gunk can accumulate on the stopper, contributing to the unpleasant smell. Use warm soapy water and a brush to scrub away any residue, then rinse it well before reinstalling.

2. Flush the Drain
Pour boiling water down the drain to flush out any built-up grime and bacteria. This will help eliminate odor-causing substances and freshen up the drain. Repeat this process a few times to ensure a thorough cleanse.

3. Utilize Baking Soda and Vinegar
One of the most effective methods for removing odor from sink drains is by using a combination of baking soda and vinegar. Start by pouring a cup of baking soda down the drain, followed by a cup of white vinegar. The mixture will create a fizzy reaction that helps break down organic matter and neutralize odors. Leave it for about 15 minutes before flushing with hot water.

4. Try Lemon Juice
Lemon juice is a natural deodorizer and can help eliminate unpleasant smells from your sink drain. Squeeze the juice of one lemon down the drain, allowing it to sit for a few minutes. Follow up with hot water to flush away the residue and leave behind a fresh citrus scent.

5. Use an Enzyme Cleaner
Enzyme-based drain cleaners are specifically designed to break down organic matter, such as food particles and grease, that can cause odors. Follow the instructions on the product and pour it down the drain. Allow it to sit for the recommended time before rinsing with hot water.

6. Clean the P-Trap
If the smell persists, it might be necessary to clean the P-trap, a curved pipe beneath the sink that traps debris and prevents it from entering the main drainage system. Place a bucket beneath the trap to catch any water or debris, then unscrew the slip nuts at each end of the trap. Remove it and clean it thoroughly using a brush and warm soapy water. Reassemble the trap and run hot water to flush out any remaining residue.
