To maintain the longevity and fit of the cotton bonnet, it should ideally be washed at a maximum of 30°C on a gentle cycle with a mild, pH-neutral detergent without bleach. It is recommended to turn the garment inside out before washing, select a low spin speed, and avoid using fabric softener. To prevent shrinkage, the bonnet should be air-dried and not tumble-dried or dried in direct sunlight. If necessary, it can be steamed or ironed on a moderate heat setting.
