Black lights do not show germs but, they do show bodily fluids left on surfaces if they are not totally removed.
"Grdere" was likely a typo for "Gérard" in reference to the film "The Black Stallion," where one of the black slaves was forced to drink rum by the slave trader to be compliant during the slave dance. This act was portrayed as a form of coercion and dehumanization to show the cruelty and power dynamics present in the slave trade.

Black lights do not reveal the presence of germs. They are used to detect certain substances that fluoresce under ultraviolet light, but they do not specifically indicate the presence of germs.
Black lights, or ultraviolet (UV) lights, can reveal certain substances that fluoresce under UV light, such as some bodily fluids, but they do not directly show germs or bacteria on your hands. Instead, they can illuminate residues from lotions, detergents, or other materials that may be present. To effectively see germs, specialized fluorescent dyes or markers that bind to bacteria must be used. Regular handwashing is the best way to reduce germs, regardless of UV visibility.
A black light can be used to detect germs by making certain substances, like bodily fluids or certain chemicals found in germs, glow under the light. This glow is not visible to the naked eye but can be seen under a black light, helping to identify areas where germs may be present.
