If you live anywhere along the coast, you already know that coastal living comes with incredible perks: fresh ocean breeze, breathtaking views, and the calming sound of crashing waves. But it also comes with a unique, relentless roommate: coastal humidity.

In marine climates, persistent fog, damp ocean air, and salt water create the perfect breeding ground for mold and mildew. Left unchecked, dampness can quickly sour bath towels, ruin favorite hoodies, and create a musty smell in closets that seems impossible to shake.

To help you protect your wardrobe, linens, and home, here are five practical coastal living hacks to stop mold and mildew in their tracks.

1. Upgrade Your Closet Airflow (and Ditch the Plastic): Closets are often ground zero for mildew because they combine trapped moisture with dark, stagnant air.

  • Ditch the plastic dry-cleaning bags immediately: Plastic traps moisture against fabric, creating a micro-greenhouse for mold spores.
  • Leave space between hangers: Overstuffing closets prevents air circulation. Give your clothing breathing room so lingering dampness can evaporate.
  • Add natural moisture absorbers: Place cedar blocks, activated charcoal bags, or hanging moisture absorbers inside closets and drawers to draw excess humidity out of the air.

2. Master the "Ocean-Exposed" Wash Routine: Saltwater, beach sand, and damp coastal air require a slightly different washing strategy than inland laundry.

  • Never leave damp towels or gear in a pile: Leaving wet towels, wetsuits, or foggy-day jackets in a hamper for even 24 hours invites mildew growth that is difficult to wash out. Hang them up to air out before putting them in the laundry basket.
  • Wash in warm water with vinegar: When washing items exposed to heavy marine moisture, add 1/2 cup of white distilled vinegar to the rinse cycle. Vinegar naturally neutralizes mold spores and eliminates stubborn musty odors without damaging fabrics.

3. High-Temp Heavy-Duty Drying is Essential: In coastal environments, line-drying clothes outdoors often backfires due to lingering marine fog and high ambient humidity. Clothes can sit damp for hours, absorbing ocean air instead of drying crisp and clean.

  • To thoroughly kill mildew spores and remove deep-set moisture, high-heat mechanical drying is key—especially for heavy items like bath sheets, fleece jackets, and bedding.
  • Pro Tip: Make sure garments are 100% dry before folding and storing them away. Storing clothes that are even 5% damp in a drawer will result in a musty smell within days.

4. Deep-Clean Heavy Linens & Comforters Regularly: Thick items like down comforters, heavy blankets, and mattress pads absorb a massive amount of atmospheric moisture over time. Residential home washers and dryers often lack the capacity or heating power to fully wash and dry these bulky items, leaving damp spots hidden deep inside the filling.

Taking bulky household linens to high-capacity commercial equipment ensures high-temp washing penetrates deep into fibers and high-volume airflow dries every single layer completely.

5. Sanitize Your Washing Machine Monthly: Your washing machine works hard to clean damp coastal clothes, but in humid environments, the machine itself can become a source of mold—especially front-loading washers with rubber door gaskets.

  • Wipe down the rubber seal and leave the washer door open after every load to let the drum dry out fully.
  • Run a monthly hot cleaning cycle using a cup of white vinegar or a washer cleaning tablet to keep the machine fresh and spore-free.
