I think the reason most don't let it sit long enough outside of using it on bathroom surfaces is when using it in the kitchen they usually go in there to prepare food, most people don't stop to think I should go wipe down the kitchen before I have to fix supper. I guess one could wipe everything down the night before but then maybe they are afraid they'll forget to wipe the surface again to get the chemical off which could be just as bad in the long run continually disgusting bits of bleach for years.
