We've previously mentioned that kitty litter does the trick when you wande-stink smelly shoes or eliminate garbage bin odours. How-to illustrator Yumi Sakugawa notes that it works well in several other situations as well.
If you're out of bicarb soda, a bowl of kitty litter will do the trick just as well. It also works wonders on nappy pails, musty old books, and even a smelly car. You can dump kitty litter pretty much anywhere that stinks and just toss it out (or vacuum it up, if necessary) once it absorbs the smell. Just don't keep it around too long because it can become damp and gross. In the case of the garbage can, changing it weekly is best. In the fridge, you can go about a month (just as you would with bicarb soda).
