You need:

2 Alka-Seltzer tablets
1 tablespoon of vinegar
Put the tablets in the drain, then pour the vinegar over them. Make sure both products go down the drain.

Cover the drain with a lid and let it sit for a few minutes. In reality, it only takes a few seconds for the solution to clear the clogged drain. However, to take advantage of its ability to eliminate bad odors, let it sit for a few minutes before turning on the hot water.

After a few minutes, turn on the hot water tap and let it run for a few seconds. This will not only remove food residue but also bad odors.

This is one of the quickest and most effective tips for unclogging a clogged drain and eliminating bad odors: put it into practice right away to have a fragrant home.
