When it comes to sanitizing a sponge, heat is your best friend. And the good news is: you already have everything you need at home.
The microwave is one of the most effective cleaning solutions. For best results, the sponge must be completely soaked in water. Then, place it in the microwave at full power for one minute. The steam generated will do the deep cleaning. Just be careful never to use a dry sponge or one containing metal parts.
The dishwasher is an excellent alternative. A complete cycle at high temperature, with drying, achieves a very similar result. Simply place the sponge in the top rack and start the program.
Finally, boiling water remains a reliable option. Soak the sponge in a pan of simmering water for about five minutes. It's simple, economical, and remarkably effective for regular cleaning.
