Clean the mat with a damp cloth and mild detergent, making sure to dry it completely before the next use. Store the mat and acupressure cushion in a cool, dry place. For cleaning, remove the foam core and gently hand wash the cotton cover with water up to 104°F maximum. The cotton cover can also be flipped over for cleaning. Do not machine wash or tumble dry to avoid damaging the pressure spikes. Air dry only.
