|Here are my sponges before and after the disinfecting. It's hard to tell with the iPhone picture, but before hand the sponges were very stiff, thin, and not very absorbent. The "before" sponges are wet, so you can see how thin they are.|
What you need:
Step 2: Put the vinegar in the Tupperware, I free hand this part, but I would say its about a cup of vinegar.
Step 3: Put on the lid (if you have a vent tab make sure it's open) and put the Tupperware with sponges in the microwave, and cook for 10 minutes.
