Your spit isn't much different than laundry detergent! Have you ever noticed how many household detergents claim that they are packed with "stain fighting enzymes"? Those are actually digestive enzymes like amylase and lipase, which break down starch and fat respectively. If you have any ambitions of saving laundry costs by shoving your dirty clothes in your mouth, though, we're sorry to burst your bubble. Spit doesn't work as a stain remover, in spite of the fact that it contains many of the same components. |
