Removing yellow stains from fabric with blue light

  Interesting that blue light is enough! Sun drying clothes is the most effective way to get rid of annoying stains, as any Mediterranean parents would know (UV cleans even better than blue light!).

    In the tests they’ve conducted the blue light had better results than the ordinary UV light.

      That's quite surprisingly!

  As an aside, I recently learned infants can get treated for hyperbilirubinemia using a special blue light[1]. As I was told, it was discovered when someone noticed babies with hyperbilirubinemia that lay closer to windows in the hospital ward faired better than those further away from the windows.
