B. Flush the drain with hot water

C. Use natural remedies like baking soda and vinegar

Baking soda and vinegar are powerful natural remedies that can effectively eliminate odors. Start by pouring half a cup of baking soda down the drain, followed by one cup of vinegar. Let the mixture fizz and work its magic for about 10 minutes before flushing it with hot water. This combination helps break down organic matter and neutralize odors.

D. Utilize chemical drain cleaners cautiously

Chemical drain cleaners can be effective in unclogging drains and eliminating odors. However, exercise caution when using them, as they can be harsh on your pipes and harmful if mishandled. Follow the instructions carefully and consider wearing protective gloves and eyewear. It’s always best to opt for natural alternatives first before resorting to chemical cleaners.

E. Clean the drain trap

In some cases, a stinky drain may be caused by a clogged or dirty drain trap. The drain trap is a U-shaped pipe located beneath your sink that traps debris and prevents sewer gases from entering your home. Unscrew the trap and clean it thoroughly, removing any accumulated gunk or residue. Reattach the trap securely and check if the odor persists.

F. Consider seeking professional help if necessary

If you’ve tried the above methods and the smell persists, it may be time to seek professional assistance. A plumber can evaluate the issue more comprehensively and offer appropriate solutions based on their expertise. Don’t hesitate to reach out for professional help if needed.

Once you’ve successfully eliminated the stinky drain, you’ll want to prevent the issue from recurring. Follow these preventive measures to keep your drain fresh and odor-free:

  • Regularly clean your drains using a mixture of baking soda and vinegar
  • Avoid pouring grease, oil, or food scraps down the drain
