3. Disinfecting and Cleaning a Sponge in the Microwave

The mechanism is simple, the microwave produces radio-frequency waves that cause water molecules in an object to vibrate, thus making friction between them and such friction induces heat. High heat can kill germs and disinfect your sponge.

However, do not just put your dry sponge into the microwave. Keep in mind that radio-frequency waves vibrate the water molecules, and therefore, a dry sponge can cause a fire. Also, make sure that your sponge is microwave-safe. Some sponges contain metal wires that can cause an explosion if put in the microwave. With these sponges, you can look through other options within the article to disinfect them.

4. Disinfecting and Cleaning a Sponge in Boiling Water

High heat kills germs. It’s simple. So if you don’t own a microwave, or are afraid that you might cause a fire, then try a more simple way: boiling water!

 And the same can be applied to your household sponge! You will just need to boil the water first, put your sponge in and boil for at least another 5 minutes. After that, let the temperature cool down then ring out the excess water and you are done.

Run your dishwasher through a heat-dry cycle while the sponge sits on the top rack. The higher temperature the better. Use your normal dishwashing soap, or preferably an antibacterial one.

You can put the sponge onto the rack with other dishes as well to save energy. However, check in advance to see if there are any large chunks of food left. Pick them off will make the cleaning process easier and more effective.
