why does baking soda and vinegar unclog the drain?

I have a clean-out plug in the basement, directly below the kitchen sink. From there, the drain seems to wander around under the basement floor until it finds the main drain. (It probably vetures under your house too at some point.) Snaking from there sometimes reaches clogs.Like some others here, I'm skeptical about mild chemicals attacking ferocious clogs. The "explanation" that I would offer is that IF it works it's because of a combination of three factors: reaction of acid with whatever acid reacts with, reaction of bicarbonate with whatever bicarbonate reacts with, and mechanical action provided by carbon-dioxide pressure.

Of course prevention is the best cure. Saving water can cost you in the long run. Just putting a little more water down the drain every time you use it can help a lot. We had a clog at work last week and I couldn't get the strainer off but a good squirt from the hose was all it needed to clear it.

My question is: How are you getting food and hair in the same drain?
