Any microfiber cloth should work as long as it’s clean. The one that came with my Skydio is just like ones for cleaning eyeglasses. I just gently wipe the lenses with the dry cloth. If the lens has visible dirt it’s probably a good idea to gently brush or blow it off before wiping it.Hi there everyone! First flight today! exhilarating! However I cannot locate the microfiber cleaning cloth. Can any microfiber cloth work or does it need to be special? Does anyone apply a liquid lens cleaner? thank you any
