To wash the OOLER Hydronic Pad, use a front-loading washing machine (one without an agitator). Secure the pad tubes with a thick rubber band, rope, etc. Wash with cold water on delicate cycle. To dry the pad, keep the pad tubes secured and dry on delicate cycle with no heat. Do not bleach, do not iron, and do not dry-clean the pad. Make sure the pad is completely dry before reconnecting to a power source.
