Amy to be perfectly honest I usually wouldn't bother watching a video like that as I am just tooo lazy to BUT I did watch it and I learned a couple things. I am cleaning my sponge correctly in the microwave (99.9% less bacteria is good enough for me). I did learn that those antibacterial dish washing up liquids only kill the germs on your hands , it doesn't work for the dish... that was news to me,, never gave it a thought. But will not be buying them anymore as they are more expensive and since they don't work.. LOL Next I don't drink drip or percolated coffee so no worry for me there... but good to know it's too acidic to go bad in case I'm at someone's home and they serve it... LOL The only thing is I do clean my st/st sink more than once a week and will continue to do so. Now my mind hit brain fade mode... but it was a good video and thank you!
