You will surely have happened to bring your nose close to the sink drain and perceive a very unpleasant bad smell. The classic “pipe smell” is a very frequent problem that can be caused by many different factors.
The stench in the sink drain is almost always caused by the accumulation of residues of food, drinks and hygiene products (toothpaste, soap, detergents, etc.), which stick to the walls of the siphon generating volatile aldehydes with a very unpleasant smell.
Also, when the sink is not used for a while, the siphons dry out. When used again, it releases gases that are the result of fermentation and cause bad smell.
Fortunately, there are very useful methods to eliminate the stench from the sink drain, and below we suggest the 4 most effective.
1. Vinegar and salt
One of the most effective natural tricks to get rid of the stench from the sink drain is to pour a very generous amount of salt into it, then a liter of hot water and half a liter of white vinegar. Cover the drain with a lid and wait 30 minutes.
After the set time, pour a generous amount of hot water to complete the cleaning of the siphon and eliminate bad odors.
2. Vinegar and baking soda
This formula is also one of the most effective for eliminating bad odor from cooking or bathing. Pour 230 grams of baking soda and half a liter of vinegar into the sink drain.
An effervescent reaction will form that will last a few seconds, so wait for about 15 minutes and then pour in plenty of hot water.
3. Liquid ammonia
Liquid ammonia is a cleaning product that, although it is not natural and should be used very carefully, is one of the most effective against bad odors.
Put on gloves and a mask and pour a small amount of liquid ammonia down the sink drain. Wait 5 minutes, then pour in plenty of hot water. Remember to never remove gloves and mask throughout the cleaning process.
4. Coarse salt and lemon juice
Another of the best-known remedies to eliminate residues and bad odors from the sink siphon is to pour 100 grams of coarse salt and 250 ml of lemon juice into the drain.
Wait 15-20 minutes, then pour in plenty of boiling water to remove all residue. As it’s an all-natural makeup, you can apply it once a week to keep the drain clean at all times.
As you can see, the four solutions suggested above are cheap and effective and allow us to always have a sink that always smells good. If bad smells persist, it is appropriate to contact a professional to find the cause.
