It took three years and 503 pieces of his own belly button lint, but Georg Steinhauser has determined that it’s the body hair surrounding the belly button that traps fat, sweat, dust, dead skin and clothing lint and gathers it in the navel.
He concluded that there were a few ways to eliminate navel lint from accumulating:
- shave the belly hairs surrounding the navel
- wear old clothes, as they have less lint
- belly piercings, such as belly button rings, keep lint away from the navel
