How often am I supposed to replace the sponge in my kitchen? I feel like this valuable piece of information was not taught to me during childhood, and certainly was not addressed in school. In my kitchen I have two sponges: one is for washing my dishes and the other is for washing the plates with cat food. The only reason I separated the tasks into two sponges was because I bought a pack of sponges at Costco. Since Costco only sells things in packages of a billion count I figured I could use more than one at a time. Anyway, I’m pretty aggressive with my sponge-cleaning and they break apart every so often, but is there a standard amount of days or weeks I need to be replacing them? Every week? 4 weeks? 6 months? You could tell me once a year and I’d probably believe you.

I like opening the package for a new sponge and the difference between a new sponge and one I’ve been using for a week or two is quite noticeable, so I might as well just keep replacing them fairly often. That being said, I think this needs to be addressed in schools so our children know moving forward what acceptable sponge practice is.
