Most slippers are made of EVA or PVC, and there will always be an inevitable "smelly plastic smell".

1. Put the slippers in the basin and soak them in the laundry detergent for half an hour, wash them thoroughly and dry them until they are tasteless.

2. Buy some activated carbon and put it in the shoes to absorb the odor. After a few days, take the activated carbon out and wear it and there will be no odor.

3. Put the shoe drag in the basin and pour it with 100°C boiling water. In this step, use boiling water to kill most of the remaining substances on the slippers.
