Hot water is often used to solve this problem, which is why many families often pour hot water into the drain?

Especially on humid days or hot summers, bathrooms and toilets often emit a foul odor from the drain. This is a common situation that most families face, and sometimes there are also small insects flying up from the drain.

If you encounter a foul odor from the toilet drain, a common solution is to use hot water. Here's how to do it:

Step 1: Pour some hot water into the drain. The high temperature of the water will help kill small insects flying in the drain.

Step 2: Prepare a bowl and pour some baking soda into it. Baking soda not only removes oil and stains in the drain, but also has alkaline properties that can kill the eggs of small insects in the drain.

Step 3: Continue adding a little salt to the bowl. Table salt has an effective antibacterial effect.

Step 4: Pour a little dishwashing liquid into the bowl, then add a little water and stir well. Dishwashing liquid not only removes stains but also kills small insects in the drain.

Step 5: Pour the stirred solution into the drain and let it sit for about 5 minutes. Then, continue to pour in a quantity of hot water to remove stains and small insects in the drain, thereby eliminating unpleasant odors.
