    Baking soda absorbs odors and moisture. Simply get a box from the grocery store and pour it liberally all over the carpet in the room with the wet carpet smell. Gently spread the baking soda around the carpet with a broom or sponge, working the powder into the carpet as you do so. [1]
    • Allow the baking soda to remain on the carpet overnight.
    • You can also use powdered borax in a similar manner. If you use borax, follow any safety precautions on the packaging.

    Commercial carpet shampoo can also help remove a wet carpet smell. It can be found at your local grocery store or online. Follow the directions on the shampoo’s packaging, which will likely direct you to vacuum the carpet first. [3]
    • Note that some carpet shampoos are designed to be used in a carpet cleaning machine, while others can be used with a sponge.
    • For instance, you may need to sponge the shampoo into the carpet, allow it to sit for at least 20 minutes, and vacuum the entire area again.

    Plain white vinegar is extremely acidic, which gives it antibacterial, antimicrobial, and antiseptic properties. Not only can it kill mold and mildew, it can also help loosen and lift other debris from your carpet. To make a cleaning solution, mix 2 cups (0.47 L) of warm water with 1 tablespoon (15 mL) of white vinegar and 1 teaspoon (4.9 mL) of baking soda in a spray bottle. [4]
    • Shake the mixture thoroughly and apply liberally to your carpet. Make more as needed.
    • Note that the room will smell strongly of vinegar until the mixture dries.
    • Once the mixture has dried, vacuum the room completely.

    Mix 4 tablespoons (59 mL) of 3% hydrogen peroxide with 1 tablespoon (15 mL) of dye-free mild soap, such as Dr. Bronner’s. Blend them into roughly 6 cups (1.4 L) of hot water. This mixture is ideal for home carpet cleaning machines.
    • Find 3% hydrogen peroxide at a pharmacy or grocery store.
    • Hydrogen peroxide may lighten the color of darker carpets. As long as you keep the percentage of hydrogen peroxide below 3%, however, this risk is minimal.
  3. Watermark wikiHow to Get Rid of Wet Carpet Smell
    Use white vinegar and hydrogen peroxide together for extra cleaning power. Blend 1 ⁄ 4 cup (59 mL) of white vinegar with 1 tablespoon (15 mL) each of hydrogen peroxide and mild dye-free soap in a spray bottle. Fill the rest of the bottle with warm water.

    Especially when using hydrogen peroxide to clean your carpets, test your cleaning solution to ensure that you won’t accidentally cause discoloration. Simply wet a towel with your cleaning solution and rub it on the carpet in the corner of the closet, for instance. [5]
    • Let it sit for a few minutes, blot with a dry towel, and wait 24 hours. If no fading or other discoloration occurs, your mixture is likely safe to use on the rest of the carpet.

    Humidity is the primary cause of the mold and mildew that leads to wet carpet smell. As such, use a dehumidifier or air conditioner to help prevent a musty smell from developing or returning after cleaning. Alternatively, keep a fan running and windows open. [6]

    If you’ve tried getting rid of the wet carpet smell but the scent persists, it may be worth having professional carpet cleaners come take a look. They will be able to tell you whether the carpet can be cleaned and salvaged. [7]
    • A carpet cleaning company may even be able to remove and fully clean a carpet damaged by flooding or another source of persistent moisture.

    If you have a carpet that was installed with tack strips, you may be able to remove it, clean it, and reinstall it. If you or a carpet cleaning professional are able to salvage the carpet itself, the padding beneath it should still be replaced. [8]
    • If cleaning the carpet yourself, mix one part 3% hydrogen peroxide with five parts water and spray the entire carpet on both sides. Then lay it out in the direct sunlight until the carpet is fully dry.

    If water has permeated your carpet and the padding beneath it, you may need to replace it. In general, if a carpet was saturated with liquid for more than 24 hours, or if moisture has allowed mold or mildew to permeate the carpet, it will need to be replaced. [9]

      Article Summary X

      To get rid of wet carpet smell, sprinkle baking soda over the carpet, then let it sit overnight so it absorbs the bad odors. Vacuum the carpet thoroughly the next day to suck up all of the baking soda. You can also use vinegar to get rid of wet carpet smell. Just mix 1 tablespoon (15 mL) of white vinegar with 2 cups (470 mL) of water in a spray bottle and mist the carpet with it. The vinegar will kill any mold and mildew in the carpet fibers. Once it’s dry, vacuum the carpet. If the bad smell persists, you may need to use a commercial carpet shampoo. Follow the instructions on the packaging to apply it to your carpet. Some carpet shampoos can be applied with a sponge while others require a carpet cleaning machine, which you can rent from a hardware store.
