The general recommendation is to follow the washing instructions recommended by the manufacturer.
Our recommendation is to wash in 40 degrees with a soft detergent (any at the market), use no softener. If it is possible rinse it twice. Dry the garments by tumble-drying or by ironing. Use low temperature when tumble drying. The heat actually helps activate the surface treatment . Do not bleach your garments. Generally do not dry clean, but if professionally dry-cleaned, request clear distilled solvent rinse and spray repellent.
To remove a stubborn stain, test a small hidden area with a commercial stain remover before using it on a place that shows. You may find certain stains have to be removed professionally. Rinse well.
