Boiling Water for Clogs - How to Unclog a Drain - Bob Vila
Make It Hot
Plain hot water is perhaps the unsung hero of clog busting. Typical sink and tub clogs consist of grease, hair, and food residue.

One-half cup of baking soda followed by a full cup of vinegar is also an effective remedy that you can use on a regular basis.
