Well, bacteria can grow on anything moist and warm. So, choosing between sponges and dishcloths is nothing less of personal preference. However, other aspects make dishcloths a better choice. First is that dishcloths can last up to six months if you maintain them well. Second, dishcloths come in a variety of cute design, graphics, patterns, and colours that can add beauty to your dishwasher or sink. Still, we would say choosing between dishcloths, sponges, or even brushes is only your choice.
