When cleaning your extension, remove any part that is not waterproof. From there you will want to use warm water and antibacterial soap on the entire dildo, both inside and out. You can also use an anti-bacterial sex toy cleaner as a replacement for soap and water. Depending on the harness material, it may not be able to get wet. We recommend spraying an anti-bacterial sex toy cleaner on this portion or again, soap and water if waterproof. Allow your extension to air dry and then store in a cool dark place such as a nightstand. Rinse the toy under warm water. Dry the toy completely with a microfiber towel. Spray with an anti-bacterial sex toy cleaner. Let your toy dry in natural light. Store in a dark dry place or bag.
