To enhance the slip-resistant qualities of the fabric, spray with water to dampen before use. Machine wash cold with like colors. Deeper colors may require multiple, separate washings to remove excess dye.
Do not use softening essence as it will damage the fiber's absorption function.
Hang to dry. Do not bleach. Do not use dryer sheets, fabric softeners or detergents with fabric softener, as they will make the surface of towel slick. Because some dye loss may continue beyond the initial separate washings, and so should be careful when practicing on light colored mats or in light colored clothing.
