We highly recommend you hand wash your bottle & silicone inserts with warm soapy water, rinse, then leave to dry or use a soft towel to dry. Go old school on this and don't use the dishwasher. Your bottles have easy twist off tops and bottoms for easy cleaning. When putting your crystal water bottle back together, ensure that everything is nice & dry. Only fill with cool/cold water. As your bottle is made of high quality Borosilicate Glass, it is quite tough, however you still need to be careful as with any glass product. Do not put your crystal water bottle in the freezer or the microwave. The wands are secured via the silicone insert, you just need to push the wand (up and into) through the insert, when replacing your wand.
