Do you know the twelve (12), dirtiest things in the kitchen? I admit I read the article but, 3 of them floored me that people didn't know. 2 of them I was surprised at. I'll list them in an answer later in the day.

I don't know what the DIRTIEST would be my mind could only guess probably counter/table tops, and I would think handles like sink handles, fridge handles, frying pan handles, etc. Probably the inside of a mitt is on there. I am also gonna add light switches. ((((((( shudders ))))))

I know the sink and sponge have to be on there. Probably the handle to the fridge as well. Maybe the keypad on the microwave?

For my sponge I throw it in the dishwasher when I do the dishes and run it on sanitize.
