Got a smelly sponge? Try this easy tip to refresh that sponge instead of tossing it and buying a new one:
Soak the sponge in a bowl of water with 2 tsp. lemon juice for a few minutes. Then heat the sponge in the microwave for 30 seconds. Let it cool for about 5 minutes before taking it out -- the sponge will be hot, so be careful!
The acid in the juice works with the heat to get rid of the germs, leaving you with a clean fresh smelling sponge once again!
