I’m going to admit something that some might completely cringe at….I am not good at changing out the scrub sponge on my dish brush. Its some where around the time the smell of mildew hits my nose that I figure it might be time for a new one. Today I was frantically scrubbing my daughter’s favorite cup, because she demanded that no other would do, and I started thinking about the possibility of that sponge being tainted with colonies of germs.
