These Scotchbrite sponges were always a mainstay in my parents kitchen. I believe that its due to the scrubbing side of the sponge. I do agree that the scrubber is great for getting stuck on gunk off of your pots and pans, and the sponge side works well too. I personally though, don't care for these because they have a tendency to hold on to smells and they can take a long time to dry. I don't want to seem completely negative about these sponges because they are good, they're just not my personal preference.
