Fixing Musty Clothes in Humid Weather | Generated by AI

Home 2026.03

Question: In March in Guangzhou, with humid and sometimes rainy weather, clothes don’t dry properly after hanging for a day and still feel wet. Using the cool mode on a Haier dryer didn’t dry 10 clothes after 2 hours, then they stayed inside for about 10 hours, and even after using L-2 hot mode for another 2 hours, they still smell bad. What should I do? Should I wash them again and then use L-2 hot to dry?

Answer:

Yes, the bad smell (likely musty or mildew-like) is almost certainly from bacteria and mold growth caused by the clothes staying damp for too long. In Guangzhou’s March weather, with typical relative humidity around 76-83% and frequent rain, drying is difficult, and moisture lingers in fabrics. The “cool mode” on your Haier dryer (probably a low-heat or air-dry setting) is too weak to remove enough moisture in humid conditions or with a full load of 10 items, so the clothes never got fully dry. Leaving them sitting damp inside the dryer for 10 hours made the problem much worse, as warm, moist, low-airflow conditions inside encourage rapid bacterial growth and odor.

Running L-2 hot (likely a medium-hot timed or level-2 heating mode) afterward couldn’t fully remove the already-set-in smell, even if it dried the surface, because the odor-causing compounds are now embedded.

Recommended steps to fix this:

  1. Rewash the clothes — This is the most reliable way to remove the mildew/bacteria causing the smell. Do not just re-dry without washing, as heat alone often locks in or fails to eliminate established musty odors.

  2. Use one of these effective odor-removal washes (choose based on what you have):
    • Add 1 cup (about 250 ml) of white vinegar to the wash cycle (put it directly in the drum or fabric softener compartment). Vinegar kills mildew and neutralizes odors without leaving a strong smell after rinsing.
    • Or add ½–1 cup of baking soda to the wash (with normal detergent) — it absorbs and deodorizes.
    • Best combo (if smell is strong): Wash first with vinegar, then do a second wash with baking soda + detergent.
    • Use warm or hot water if the clothes allow it (check labels), as higher temperature helps kill bacteria better than cold.
  3. Dry properly after washing:
    • Use your Haier dryer’s hotter setting right away (L-2 hot or the highest heat level suitable for the fabrics).
    • Avoid overloading — dry in smaller batches (e.g., 5–6 items) so air circulates better and drying is faster/more even.
    • Run an extra cycle if needed; make sure they are 100% bone-dry before removing (feel seams, thick parts, and inside pockets).
    • If possible, add 30–60 extra minutes on hot to ensure complete dryness.
  4. Extra tips to prevent this in the future in humid Guangzhou weather:
    • Never use cool/low-heat mode for full or heavy loads in high humidity — it often leaves clothes damp.
    • Switch to hot/heated modes (like L-2 or higher) from the start for reliable drying.
    • Clean the dryer’s lint filter before every load and check if the vent/exhaust is blocked (poor venting traps humid air and causes smells).
    • If the dryer still struggles, consider running a shorter wash → immediate hot dry cycle, or use a dehumidifier in the laundry area to help overall.
    • Avoid letting wet clothes sit anywhere (washer, dryer, or basket) for hours.

With a good re-wash + vinegar or baking soda + thorough hot drying, the smell should come out completely in one or two cycles. If it still lingers faintly after that, repeat the vinegar wash once more.
