You can also deodorize drains and help smelly drains with a combination of baking soda and vinegar. These ingredients, when used together, can also sometimes help to clear drain clogs.
Baking soda and vinegar do not effectively unclog drains. Instead of clearing debris, mixing them chemically neutralizes both ingredients into salt water. The fizzing reaction is visually satisfying but largely escapes upwards, offering zero power to dissolve grease, hair, or stubborn sludge.
A rotten egg (sulfur) smell in your shower is usually caused by hydrogen sulfide gas created by bacteria feeding on trapped hair, soap scum, and grime (biofilm) inside your drain. Occasionally, it can also signal a dry water trap or a failing water heater.
