I've been using this for about a year (once a week), but I'm selling it because I haven't had time to use it since my child was born. There are no noticeable stains or mold. Also, I only used steam with water. 【High-Quality Steam】 The nanocare facial steamer provides gentle steam for the skin, making it ideal for moisturizing and cleansing. 【Design】 It has an elegant white color that matches any interior. Its compact size makes it convenient for storage. 【Ease of Use】 With simple operation, even beginners can easily use it. The steam output can also be adjusted to suit your preferences. - Brand: nanocare - Color: White - Type: Facial Steamer Thank you for viewing.
