  5. Rinse the area with clean water.
  6. Let the area dry completely.

Leaky pipes

If leaky pipes are the cause of the smell, you’ll need to fix the leak. You can do this yourself or call a plumber.

Rotting food

If rotting food is the cause of the smell, you’ll need to find and dispose of the food. You can also use a deodorizer to help remove the smell.

  • Check your pipes regularly for leaks.
  • Keep the area under your sink clean and dry.
  • Store food in airtight containers.

Additional tips

Here are a few additional tips that may help you get rid of the musty smell under your sink:

  1. Using a fan for air circulation:

A small, battery-powered fan can be a game-changer in preventing musty smells under your sink. The constant airflow helps to:

  • Evaporate moisture: Dampness is like an invitation for mold and mildew to thrive. A fan whisks away excess moisture, keeping the environment less hospitable for these unwanted guests.
  • Prevent stagnant air: Musty smells often linger in stagnant air. A fan keeps the air circulating, diluting and dispersing any unpleasant odors.
  • Promote overall dryness: Good air circulation promotes faster drying after cleaning or spills, further reducing the risk of mold growth.
  1. Placing a moisture absorber in the cabinet:

Moisture absorbers are handy little packets filled with hygroscopic materials like silica gel or activated charcoal. These materials attract and trap moisture from the air, keeping the environment under the sink drier. This dryness discourages mold growth and prevents musty smells from taking hold.

Here’s how to use moisture absorbers effectively:

  • Choose the right size: Select an absorber suitable for the space under your sink. Small cabinets might only need one packet, while larger ones might require two or more.
  • Position strategically: Place the absorber near potential moisture sources, like leaky pipes or areas where condensation tends to form.
  • Replace regularly: Most moisture absorbers lose their effectiveness after a while. Check the manufacturer’s instructions for recommended replacement intervals, typically around 30-60 days.
  1. Painting with mold-resistant paint:

For a more permanent solution, consider painting the inside of your sink cabinet with a mold-resistant paint. These paints contain special additives that inhibit mold growth and spore formation. They’re especially helpful if you’ve had persistent mold issues or want to prevent them altogether.

When choosing a mold-resistant paint, look for one with the following features:

  • EPA registration: Ensure the paint is registered with the Environmental Protection Agency (EPA) for effective mold control.
  • Fungicidal properties: Choose a paint with fungicidal properties that kill mold spores on contact.
  • Moisture-resistant: Opt for a paint that provides a moisture barrier, discouraging future mold growth.

Remember, proper preparation is key before painting. Thoroughly clean and dry the cabinet to remove any existing mold or mildew. Apply the paint in well-ventilated areas and follow the manufacturer’s instructions for optimal results.

By combining these strategies, you can create a hostile environment for mold and musty smells under your kitchen sink, ensuring a fresh and fragrant space for years to come.
