Drain De-Clogger Recipe:  1/2 cup baking soda  1 cup vinegar  1 gallon boiling water  Carefully siphon all the baking soda down the drain. Pour in 1/2 of the vinegar, covering the hole so the fizz is forced down, not up (omit this for toilets, please!). Add the second half of the vinegar, following the same procedure. Allow to sit for 15 minutes or so, and then flush with an entire gallon of boiling water.
