If you like to use a sponge to clean around your house, you might be surprised at the number of germs that like to grow in your sponge. However, you can easily clean your sponges by microwaving them. Microwaving a wet sponge can kill up to 99.9% of germs in your sponge, and you should probably be disinfecting it every day.
You should still replace your sponge with a new one every two weeks to a month.
Here's how it Works:
Rinse all the soap from your sponge and make sure that it's completely wet. Microwave a scrub sponge for 1 minute or a cellulose sponge for 2 minutes. Be sure to watch it to make sure it doesn't catch on fire (which it shouldn't if it's wet). Let it cool in the microwave and store in a clean spot.
Obviously, use common sense when microwaving. Don't microwave a sponge with any metallic parts or they'll spark.
Can you Sanitize your Sponge with Vinegar?
Yes, you can soak your sponge over night in 1 cup hot water, ½ cup white distilled vinegar and 3 tablespoons salt. You can also sanitize your sponge with a diluted bleach mixture (½ cup of bleach to 1 gallon of water).
Will Boiling Your Sponge Work Also?
Yes, you can soak your sponge in boiling water for about 30 minutes to kill bacteria. But, the microwaving trick is easier.
