How to eliminate the smell of kettle plug?

1, milk deodorization method: first clean it with detergent, then pour two tablespoons of fresh milk into a plastic cup, cover it, shake it to make every corner of the cup contact with the milk for about one minute, and finally pour out the milk and clean the cup.

2, orange peel deodorization method: first clean with detergent, then put fresh orange peel into the pot, cover, rinse for about 3 to 4 hours.

If none of the above methods can remove the odor of the plastic cup, and the cup emits a strong pungent smell when it is flushed with hot water, then you can consider not drinking the water from this cup. Maybe the plastic material of the cup is not good, and drinking the water inside may be harmful to your health. It's safer to give it up and replace it with a cup.
