I tried washing my stainles sink with nothing but a lemon and baking soda. I caught a few minutes of Martha Stweart one day last week and she was showing natural ways fo cleaning instead of using harsh chemicals. Anyhoo, I think it worked. I think. I don't know. At least with the smelly harsh chemicals I know I wiped out any existing germs. What could stand up to that stuff?! So I'm wondering what natural stuff works?
