Using your Zoned Dough® Aromatherapy Pillow is a breeze. Just place it on your bed and lay your head on it. If you have a King or Queen size pillow, you can use the included peppermint spritzer to refresh the aroma every now and then. Simply give the pillow a few spritzes to enjoy the renewed peppermint scent. When it comes to cleaning, spot - clean the Tencel® mesh cover with a mild detergent and let it air dry. Avoid machine - washing or drying the cover as it may damage the fabric. Keep the pillow away from direct sunlight and high - heat sources to maintain the integrity of the memory foam and the peppermint oil. If you're using the travel size pillow, remember it doesn't come with a spritzer, but the peppermint infusion in the foam will still offer its relaxing benefits.
