Why does a belly button smell? What do u do to make the smell stop?

BELLY BUTTON SMELLS. The belly button is a difficult body part to clean. It's a catch-all for dirt, lint, sweat, dead skin cells, bacteria & yeast germs, as well as fibers from clothing. It's also locked up without air. Like limburger cheese! whew! get a few q-tips, dip them into rubbing alcohol or hydrogen peroxide & very gently swab the inside of the belly-button at least once daily. And then dry thoroughly.
