Wholesale Silicone Bottle Brush, Water Bottle Cleaner Brush for Stanley, Hydroflasks, Glass, Thermos Sports Bottle, Vase and Glassware, Bottle Brush Cleaner for Small Narrow Neck Containers (2 Pack Grey+White)

* HOW TO USE: Be aware that silicone is non-absorbent, so it CANNOT hold soap, lather up or get sudsy like a sponge. For optimum cleaning results when using our bottle brush, first add warm, soapy water to your container, and then scrub away. The minimum diameter neck the brush will squeeze into is 1 1/8” wide, so it won't fit in beer, wine, swing-top or kombucha bottles. * DEEP CLEANING POWER: With its 12.5” long, non-flexible steel shaft and rugged silicone bristle head, our water bottle brush gets deep down into tall, narrow containers such as insulated water bottles, flasks, thermoses, baby bottles, vases and skinny glassware. * BETTER HYGIENE FOR YOU: Our silicone water bottle cleaner repels unpleasant odors and stains - unlike sponge and nylon brushes that fall apart, and get smelly after a few uses.
