Lifestyle Desk – The scorching summer season is going on and the importance of air coolers increases in every house. Especially for middle class families, a cooler is no less than an AC. This is the easiest means of providing relief at low expense. But many times, as soon as the cooler is turned on, a strange fishy smell starts spreading in the room, which spoils the entire atmosphere. This problem not only makes one feel uncomfortable, but can also be harmful for health. Let us know its reasons and how to deal with this problem.

Causes of bad smell from cooler

The main reasons for this foul smell coming from the cooler are the old water accumulated in its tank, algae, and fungus and bacteria that grow due to moisture. If the cooler is not cleaned for a long time, this dirt keeps increasing and keeps spreading in the room with the air. In such a situation, it is important to take care of the cooler from time to time. If you are also struggling with this problem, then by adopting some easy home remedies you can make the cooler capable of providing fresh air again.

clean regularly

The first and most important step is regular cleaning of the cooler tank. Switch off the cooler and drain out the old water completely. After this wash the tank with clean water. If there is a lot of algae in the tank, you can clean it gently with the help of a brush.

use vinegar

After this, the second effective solution is the use of vinegar. After filling the tank with water, add a cup of white vinegar in it and run the cooler for 10-15 minutes. Vinegar helps eliminate bacteria and fungus and removes odor.

Baking soda will also work

Baking soda can also be used to deal with this smelly problem. It is a natural cleaner that absorbs odors. Mixing one to two spoons of baking soda in cooler water and running it reduces the smell.

Cleaning of cooling pad also

It is very important to clean the grass (cooling pad) of the cooler from time to time. If the pads are too old or damaged, it is better to replace them. Dirty pads also become a major cause of bad smell.

add neem oil

Neem oil or a few drops of any antiseptic liquid can also be mixed in water. This reduces the growth of bacteria and keeps the air fresh.

change water daily

It is important to keep in mind that the water in the cooler should be changed daily or every other day. Using the same water for a long time increases the problem of bad smell.
