All they need is normal clothing care.
One of the advantages of our garments is that they do not need special care for their washing and maintenance. You will find that by the time your shirt comes out of the spin dry cycle in the washer, it's already nearly dry.
However, some pinpoints for best results:
1. Make sure your sweat proof undershirts are inside out when you put them in the washer. This allows the water and detergent to make unimpeded contact with the areas of sweat protection.
2. Wash in water under 40℃ on a low cycle with similar colors.
3. Line dry. Do not dry clean.
4. Always use the recommended amount of your regular detergent.
5.Do not use bleach or vinegar.
*Please check the care instructions specified on the label of your shirt.
