How to remove the smell of perfume bottles

I believe that many people have such troubles. After using up the perfume, they want to use a perfume bottle to fill another perfume, but how to remove the smell in the perfume bottle? Let's take everyone to understand it!

1. Wash several times with hot water and detergent. If the smell has not been removed, proceed to step 2.

2. Add a little salt or baking soda, add hot water, let it stand for a few hours, and then rinse with warm water.

3. If it still smells, go to the drugstore to buy rubbing alcohol, and let it stand overnight after infusion. If it is a bottle with a strong flavor, it can be longer.

4. Add water to the pot and soak the bottle so that it is completely submerged in water. Bring to a boil, cook for about 15 minutes, then remove it and let it cool.
