If you are using baking soda because your drain is slow, the boiling water actually does most of the work. For a more effective mechanical clean, skip the vinegar and use this combo instead: The most common technique involves a chemical reaction

fizzing action physically agitates and loosens debris stuck to the pipe walls. The "Dynamic Duo" Method This is the standard procedure for general maintenance or slow drains. What you need: 1/2 cup Baking soda 1/2 cup White vinegar Boiling water (a full kettle) The Steps: Prep with Heat: Pour a kettle of boiling water down the drain.
