Simply install the brush into the base, place your cup over it, press the button, and enjoy a clean, shiny result in seconds. The versatile brush works on a wide variety of drinkware, including glass cups, coffee mugs, thermos cups, tea cups, baby bottles, and wine glasses. Made from food-grade materials, it is safe and durable for everyday use. The splash-proof base keeps your countertop dry during cleaning, while the smart hanging design lets the brush drain and dry between uses, saving valuable counter space.
