"Your sponges might be making your dishes dirtier. If you’re not regularly sanitizing your sponges, you could just be wiping your dishes and counters with bacteria.
Keep your sponges away from raw meat. If you're dealing with leftovers of meat juice, use a paper towel instead. To properly sanitize your sponges, immerse them in boiling water for five minutes. Alternatively, soak a sponge in water and heat it on high in a microwave for one minute, or pop it into the dishwasher with a heated dry cycle."
