http://www.snopes.com/critters/crusader/swiffer.asp I take things like this 'with a grain of salt'. I don't use the Swiffer Wet Jet. I have one of the Grab-It whatever ya call it (?) and hardly even use that. I clean mostly with bleach and water. FYI I have heard that any cleaning product with an "sol/oil" ending such as Lysol, Lestoil etc. are toxic, but haven't researched that through snopes etc. yet. No time to clean anyway!
