Save Your Sponges From A Grimy Death

If your kitchen sponge has become dirty and gross, don’t throw it away just yet. Fill a bowl with salt water–about 1/4 cup of salt per two cups of cold water. Toss the sponge in and let it soak overnight. By morning, you should be able to remove most of the gunk.

The salt should slowly replace all the space in the sponge, which pushes the dirt out. This trick may not work with some artificial sponges if they have large holes. If this is the case, run your sponge through the dishwasher instead.
