We recommend machine washing with cold water and like colors, tumble dry low or hang dry and do not bleach. We do not recommend using dryer sheets, fabric softeners or detergents with fabric softener, as they will make the surface of your yogitoes slick.
We use dyes that are heavy metal/azo/lead free and much better for the planet, so deeper colors may require multiple, separate washings to remove excess dye. Some dye loss may continue beyond the initial separate washings, so use caution when practicing on light colored mats or in light colored clothing. Be sure to avoid rolling up a damp yogitoes with your mat.
As a note, it is possible for shrinking to occur if washed in warm water and/or dried in heat.
