Clean a drain in 1 minute: The ultimate, effective trick

Next, pour 1 cup (200 ml) of vinegar down the drain. Let the mixture sit for about 30 minutes. During this time, you’ll notice a fizzing reaction, which will help break down clogs and eliminate odors.
While you wait, you can use a sponge to scrub the surface of the sink with the mixture to make it shine.
After 30 minutes, rinse the drain with plenty of hot water. This will help remove loose debris and ensure the drain is clear.
