Wadrobes don't like to stay dry and often attract unwanted scents (and sometimes creatures). Once easy way to solve the problem? According to how-to illlustrator Yumi Sakugawa, the answer is chalk.
Chalk absorbs moisture, as many sources attest, so it's a helpful aid to reduce dampness -- and the resulting smell in your wardrobes. Just tie up a bundle with some sturdy string and hang it where it won't brush up against your clothes. It will absorb moisture and the resulting smell.
