Baking soda and vinegarnStart by pouring ¼ cup of baking soda down the drain, and then leave it for about 10 minutes. Then, follow it with one cup of vinegar. Let the mixture fizzle and work for a few minutes, and then finish by turning on the water and running the disposal to clear out any leftover food waste.,
If you don't run any water down a particular drain for a very long time, that water can evaporate to the point where sewer smells can make their way through. All you need to do is run the water for several seconds to refill the trap, then wait a little while to see if the odor goes away.
Pour Some Bleach in It: Bleach, like other disinfectants, kills almost every species of odor-causing bacteria commonly found in drains and sewer lines. So, an easy DIY step you can take to reduce drain odor is to use bleach. To use bleach to clean your drain, fill the sink with hot water, and add a cup of bleach.5 days ago
