Avoid washing your sheets with towels and blankets as this will cause them to pill. Use a mild, liquid, biodegradable detergent. Or, if you prefer powder, make sure it has dissolved before adding your bamboo sheets to the wash. Fabric softener is not necessary with these sheets and not recommended as you may damage the sheets. Adding heat may cause shrinkage. If you must use the dryer please use a low heat and a low or gentle tumble cycle.
