Disinfecting and Cleaning Sponges
Cleaning sponges attract all kinds of germs and grime, and they can get pretty gross over time. You need to clean them regularly with a hydrogen peroxide wash to free them from all the looming bacteria in them. Soak the sponge in 3% hydrogen peroxide in its concentrated form until it’s saturated.
Wash off your sponge with water afterward. Clean and disinfect your sponges every day to prevent them from becoming germ-ridden. It is recommended to replace kitchen sponges every two weeks to once a month, depending on the frequency of use.
