Drain-O? Hell No!

I just got back from the store about 30 minutes ago. I have to drive about 20 minutes to get there. So when I discovered that I completely forgot to get Drain-O, I was miffed.
So, instead of getting in my car and going ALL. THE. WAY. BACK. THERE. I looked up homemade drain cleaner!
I unclogged my bathroom drain by mixing equal parts baking soda and white wine vinegar, pouring it down the drain, and chasing it with boiling water.
Living so close to the water, it really makes you think about where your drain drains to... and this was so easy, worked just as well as a harsh chemical cleaner, and I have no environmental guilt!
Do I even need to mention the cost efficiency?
Do this!
