Got a tangled necklace? How about a grease stain on your shirt? Baby powder is the solution (strange but true). Just sprinkle on a knotted necklace to make it come undone quicker and sprinkle it on that grease stain before putting it in the wash. Oh, and if you have a squeaky floor, another sprinkle there will make that disappear, too. Three problems solved beyond diaper rash.
