Vinegar and Baking Soda Drain Cleaner?

Empty about 1/2 box of baking soda into your drain.
Follow that with about 1/2-1 cup of vinegar.
It will boil for a few inutes.
Follow that with about 2 cups of boiling water out of a kettle.

I gave my suggestions for cleaning drains a few days ago, but maybe you missed them. I use about 1/4 cup baking soda, a cup of vinegar, and follow with a couple of cups of boiling water.Let set for a few minutes, then flush drains with cold water. There are no exact measurements, but this is approximately what I offered.

There's no recipe that I'm aware of. I just sprinkle baking soda down the drain, pour in white vinegar and keep putting in small amounts of vinegar until it stops bubbling and then rinse with hot water.
