Eliminate Germs From Sponges
Kill the germs you can't see so that your are not spreading germs when cleaning.
Keep your sponge’s germ free! Always allow to air dry to avoid mildew and growth of smelly bacteria. To kill the germs that have gathered on your nasty sponges, microwave on high for 2 minutes and let cool.
Warning: This only works for non-metal sponges! No metal in microwaves!
