If the clothes smell strong, you can try a softener.
Softeners can make clothes static and have a natural fragrance.
Wash the clothes with clean water first, then add a small amount of softener and then add clean water that has not worn the clothes.
Soak for about 10 minute and then dry.
Step 2 soak at high temperature
High temperature water can remove odor in some cases.
However, clothes generally shrink when soaked in high temperature.
There are also some clothes that are afraid of high temperature cleaning.
You can see if your material is suitable for high temperature soaking.
Usually soak for 4 hours, then wash with water and finally dry.
Step 3 soak in laundry detergent
You can soak your clothes in laundry detergent and warm water for a while, and warm water will do.
Try to soak for a while, about 3 hours, so that the clothes will have a fragrance.
Finally, wash it with clear water for several times.
