Some clothes are washed in rainy days, and they will smell strange after drying.

Sometimes, wet clothes stay like this for a long time. In an unventilated and dry environment, some cotton-padded jacket will have a lot of black spots, which are difficult to remove (the same reason that other items will become moldy in a humid environment for a long time). When washing clothes on cloudy days, it's best to spin them dry with a washing machine or squeeze the water out (only for some clothes). Some clothes can't be twisted.
