There are several ways to clean stinky drains, and one of the easiest is to flush the drain with hot water, baking soda and hot vinegar. This creates a fizzy chemical reaction that deodorizes and clears most drains in 30 minutes. The required supplies are water, baking soda, white vinegar, long cleaning gloves, a microwave oven and a microwave-safe container that holds at least 2 cups.
- Flood the drain with hot water
Flood the drain with hot water, then close the tap. The hot water loosens smelly soap scum and accumulated food residue in the pipes.
- Dump baking soda down the drain
Pour a cup of baking soda down the drain.
- Heat 2 cups of white vinegar
Pour 2 cups of white vinegar into a microwave-safe container and heat it until it is almost boiling.
- Pour the hot vinegar over the baking soda
Don protective cleaning gloves. Remove the vinegar from the microwave and pour it down the drain. This creates a strong fizzing reaction. Stand back from the hot liquid, and pour it slowly to minimize splashing.
- Wait 30 minutes
Give the chemical reaction 30 minutes to clear and deodorize the drain. Do not use the sink during this time.
- Flush the drain
Flush the drain with very hot water.
