Isn't that what they used to call "bluing?" Before the invention of chlorine and peroxide based bleaches they used to use bluing (or blueing?) to make whites look whiter.
As for the stand up terlets, I want one. Wonder what the building inspector would say. I'm tired of peeing in the laundry sink in the garage when nobody's around. It's so unsanitary. I really want a urinal. A statement to the world that this is a man's place.
