I used cold water and a liquid fabric softener both times. Seems to be well made but the straps for the foot and toe were to far back (maybe good fit if you have long toes?) so it didn?t work for us and had to return. Had to prop up the one corner but it might be because my floor is uneven. The audio quality is pretty good, and theres no static during silence. -Inside heel area wore holes through in each foot after less than 2 months of occasional pickleball use. I stored the spices on the door (its a hollow door, so I was concerned about the weight), and use the ones on the wall to store canned goods. We sent them back. These are so comfortable & so pretty & girly too! I will be ordering a different one just because I want to pull on it and not risk it ripping on me like this one did. The bottom charger is QI wireless charger for Air pods or other QI enabled wireless devices.
