Why you need to throw coffee grounds down the sink: a life hack from plumbers
Plumbers have suggested the easiest way to combat unpleasant odors from the kitchen sink. The simplest means will help to defeat them, informs Ukr.Media.
Coarse salt, baking soda, or coffee grounds instantly remove the smell of spoiled food. Pour 200 grams of any of these products into the drain and pour two liters of boiling water over it, the smell will disappear immediately.
Coffee grounds can also be used as a preventative measure. To do this, simply pour a tablespoon of coffee grounds into the drain of your sink, bathtub, or shower once a month and pour a small amount of boiling water over it.
After a few minutes, you can turn on the warm water to rinse away any remaining coffee grounds. Coffee grounds are great for absorbing odors and deodorizing pipes.
