How to Get a Mildew Smell Away From the Sink

Andrew Smith

Mildew grows in a variety of damp places, such as in and around your sink drain. This growth can cause an extremely foul odor that lingers even after you remove any visible mildew from the sink. You may not wish to pour harsh chemicals down the drain of your sink as doing so can harm the environment.

Remove mildew smells from a sink.

Combine two common household items to remove the smell of mildew in your sink drain and in the sink itself.

  1. Spray the surface of your sink with white distilled vinegar. Do not rinse the vinegar off of the sink's surface.

  2. Pour about one half cup of baking soda down the drain of the sink.

  3. Pour one cup of white distilled vinegar down the sink's drain. When you do so, foam should appear near the mouth of the drain. Wait two to three minutes until the foam subsides.

  4. Flush your drain with hot water after the foam subsides. Leave your faucet on for roughly 30 seconds when flushing the drain. You can also use two cups of boiling water to flush the drain.

  5. Flush the drain again using cold water after about five to 10 minutes.

  6. Wipe the rest of the sink with a damp cloth. Wipe again with a dry cloth to dry the sink.

  7. Inspect the sink after about 30 minutes. Repeat the process if you still notice a mildew smell.
