  1. Pour a tea kettle full of boiling water into the drain

    Bring a tea kettle full of tap water to a boil. Carefully pour the water directly into the clogged drain. Do not pour boiling water directly onto a porcelain sink. The boiling water loosens the clog.

  2. Run 2 inches of hot water into the sink

    Fill the sink with about 2 inches of hot water. The water helps form a vacuum when plunging.

  3. Plunge the sink with a cup plunger

    If the clog is in a double kitchen sink, have a helper hold the stopper in the drain in the second basin. Place a cup plunger over the clogged drain, flat against the sink bottom. Use quick thrusts to plunge the sink repeatedly. Aim for force on both the down and up strokes. Let the sink drain, and repeat until the drain runs free.

  4. Flush the drain with hot tap water

    Run hot tap water down the drain for a couple of minutes to clear away the rest of the clog.
