Made of high-quality silicone, it is soft and can flexibly adapt to various cup shapes. Whether it is an ordinary water cup, a special-shaped mug, or a thermos cup with a curve, it can fit tightly. At the same time, silicone has excellent durability and is not easy to deform or break after repeated brushing. Compared with traditional bristles, it has a longer service life and does not need to be replaced frequently, saving you costs. Its brush head is scientifically designed, and the density of silicone bristles is moderate. It can not only penetrate into the gaps and corners of the cup wall, but also effectively remove stubborn stains such as tea stains, coffee stains, and milk stains without damaging the cup body. When cleaning narrow-mouth bottles, the long handle design combined with the soft brush head can easily penetrate into the bottom of the bottle to achieve dead-angle cleaning and restore the cleanliness of the cup. Silicone itself has antibacterial properties and can inhibit the growth of bacteria. Compared with traditional cup brushes that are easy to hide dirt and breed bacteria, using a silicone cup brush can reduce the secondary contamination of bacteria on the cup and protect your health. After each use, a simple rinse can remove dirt, and it is not easy to leave residual detergent and odor, keeping itself clean at all times. The cup brush is resistant to high temperatures and can withstand high-temperature disinfection. It can also be put into the dishwasher for cleaning, which greatly simplifies the cleaning process. After daily use, just rinse it under the faucet, and the dirt will quickly fall off, making it easy to keep the brush clean and more assured for next use. Not only suitable for all kinds of cups, but also for cleaning kitchen items such as milk bottles, kettles, and juicer filters, it meets a variety of household cleaning needs. It is a powerful little helper for kitchen cleaning and brings convenience to your home cleaning.
