Hang your laundry outside to dry. The sun can help keep mold at bay — just be sure to dry everything completely (even if it means some time in the dryer inside).
Never put damp laundry in the washing pile. If you can’t wash wet or damp clothes and towels immediately, pre-treat as needed and then let them dry to avoid getting smelly.
Thicker towels and heavy clothing such as jeans take longer to dry, so be sure to dry them thoroughly each time.
