Kitchiny 12.5" Silicone Bottle Brush & Straw aner Brush Set, Bottle aner Brush for Hydro Flasks, Sports Bottles & Reusable Straws, Water Bottle Brush aner for Narrow Neck Containers

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. This bottle scrubber prevents nasty grime build-up which is more hygienic and healthier for your family NO MORE SCRATCHES: The easy-clean, non-scratching silicone bristles of our 12.5” long bottle cleaning brush are tough on gunk, yet gentle enough to leave your favorite vase, glass water bottle, pitcher, blender and delicate glassware clean and scratch-free SAY GOODBYE TO GRUNGY CONTAINERS: It’s great as a sports bottle cleaner brush, for swishing slimy dregs from your flask, scrub soup from your thermos, or blitz residue in your baby bottle. Our 12.5” long bottle brush is perfect as a travel bottle brush too! LONG LASTING & DURABLE: The sturdy bristles of the rugged bottle brushes for cleaning will keep their shape, and won’t break off or fall apart. Our long bottle brush fits in 1 1/8” width bottle necks or larger, and heat-resistant up to 400°F.
