To remove the old musty smell from inside old kitchen cabinets, you can try the following treatment options:
Cleaning: Start by thoroughly cleaning the cabinets to remove any dirt, dust, or residue that may contribute to the musty odor. Use a mixture of warm water and mild dish soap or a vinegar-water solution to wipe down the interior surfaces of the cabinets. Rinse with clean water and allow them to dry completely.
Baking Soda: Baking soda is known for its ability to absorb odors. Place an open container or a bowl filled with baking soda inside each cabinet. Leave it for several days or even a week, allowing the baking soda to absorb the musty smell. Replace the baking soda as needed until the odor is eliminated.
White Vinegar: Vinegar is an excellent natural deodorizer. Wipe down the interior of the cabinets with a cloth or sponge soaked in undiluted white vinegar. Vinegar can help neutralize the musty odor. Allow the cabinets to air dry completely.
Activated Charcoal: Another effective odor absorber is activated charcoal. Place a few pieces of activated charcoal in an open container inside each cabinet. Leave them for several days to absorb the musty smell. Remember to replace the charcoal regularly to maintain its effectiveness.
Odor Absorbing Products: There are commercial odor-absorbing products available on the market, such as odor-neutralizing gels or packets. Follow the instructions on the product and place them inside the cabinets to eliminate the musty odor.
Paint or Sealant: If the musty smell persists after cleaning and deodorizing, you may consider applying a coat of paint or sealant to the interior surfaces of the cabinets. Choose a paint or sealant that is specifically formulated to block odors. This can help seal in any remaining odors and provide a fresh scent.
Before applying any treatment or paint, ensure that the cabinets are completely dry. It's also advisable to test the treatment or paint on a small, inconspicuous area of the cabinet first to ensure it doesn't cause any discoloration or damage.
In severe cases where the musty smell persists despite these efforts, it may be necessary to consult a professional who specializes in dealing with odor remediation or consider replacing the affected cabinets if they are beyond repair.
