A set of Silicone Bottle Cleaning Brushes.

silicone bottle brush set. These sets typically include different sizes and shapes of brushes designed to clean various containers with narrow openings and hard-to-reach areas. 

Key Features and Uses

• Material: The brushes are made from food-grade, BPA-free silicone that is hygienic, durable, and resistant to odors and stains. Unlike sponges or brushes with nylon bristles, silicone does not trap and harbor bacteria.
• Design: The brushes often feature a long handle for extended reach and flexible bristles that can bend to clean all corners of a bottle without scratching the surface. Some sets also include a smaller brush for cleaning nipples and a thin wire brush for straws.
• Applications: They are commonly used for cleaning baby bottles, water bottles, sports bottles, flasks, glassware, vases, and other containers with narrow necks.
