The final step is to thoroughly flush the drain to clear out all the loosened debris and to verify that the clog is gone. After waiting for the baking soda and vinegar mixture, boil a full kettle of water. Carefully and slowly pour the boiling water directly down the drain. The heat helps to melt and flush away any remaining soap or grease. After the boiling water, turn on the bathtub's hot water faucet to its maximum flow for several minutes. Watch carefully to ensure the water is now draining quickly and continuously without backing up. If it drains well, your job is done.
