At the same time, the clothes washed have been hanging outside for many days, and all the other clothes are fine, except one that always smells wet. The weather has been very good recently.

Hello! One piece of clothing always smells damp, while other clothes are ok. The possible reasons are as follows:

1. clothes are not washed thoroughly, and there are sweat stains or stains, which will produce odor over time.

2. Insufficient ventilation and air circulation in the environment where clothes are hung, which leads to bacterial growth and odor.

3. Too long drying time of clothes, especially in humid environment, will lead to the growth of bacteria and mold on clothes and produce peculiar smell.

4. Improper use of laundry detergent or softener, using too much laundry detergent or not using proper amount of softener, resulting in the bacteria on clothes can not be thoroughly cleaned, resulting in odor.

To solve this problem, the following measures can be taken:

1. Wash the clothes with peculiar smell again, and use proper amount of laundry detergent and softener to ensure that the clothes are thoroughly washed.

2. Choose a well-ventilated place when drying clothes to ensure that clothes can get sufficient air circulation.

3. Shorten the drying time and avoid exposing clothes to wet environment for a long time.
