The ideal temperature is below 40 degrees Celsius. Shower gel, soap, and laundry detergent can all be used for cleaning. During cleaning, it’s best to wipe the head with a damp towel. Water must not get into the neck area, as this can cause rust and affect usability and appearance. The area below the neck can be directly washed with a shower. The vagina and anus can be repeatedly cleaned using the provided cleaning tool. Do not use a faucet to directly rinse the vagina. There is a waterproof ball deep inside the vagina; it is glued to the screw, and excessive washing may cause it to fall off. If it does fall off, simply dry the vagina and reattach it.
