I have used 2 - 3 tablespoons in the bottom of the kitty litter box, then fill box 1/4 full of water, swirl bleach-water around inside the pan, then rinse and wipe out to sanitize the litter box.
Our Librarian was recently diagnosed with Lupus, so to reduce the constant barrage of germs on all the books, the Librarian bought every classroom Clorox Wipes. Each classroom, prior to going to the Library, wiped down all their books that they were returning, and continue to do so the rest of this year! All the library tables were wiped down as well. I think this has also reduced the number of head colds/flu this year in the children!!
