A popular thread on Reddit called "What are some secrets about widely used products?" contains some wisdom and a lot of malarkey, predictably. But it's not all urban legend and gotcha stuff about hidden ingredients that you'd rather not be eating or drinking. Many Reddit users are just as pleased to reveal secret, little known powers of products they love.
One user expresses her great admiration for "Neutrogena Facial Soap -- the old-school yellow liquid version that comes in the pump container" which "gets out every (bleeping) stain known to mankind." Spurred to experiment after seeing Neutrogena work well removing blood stains, the user "gathered a number of different fabrics and smeared motor oil, lipstick, marker, juice and soy sauce on them, and let the Neutrogena sit on them for a while. I swear to sweet jebus, the results were amazing and worked way better than most of the laundry products in my house."
