Using Baking Soda and Vinegar to Clean Kitchen Sinks

My wife is using baking soda and vinegar to clean the kitchen sinks. She found this idea on the internet. It's a cheap, easy, better for environment and doesn't give out toxic fumes.

I'm amazed at the foaming and fizzing chemical reaction when vinegar was poured unto the baking soda in the sink. I've forgotten my chemistry, but if you are interested, you can check out the formula here.
