Silicone is non absorbent and cannot hold soap, lather up or get sudsy like a sponge. To get the optimum cleaning result 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 inch wide, so it won't fit in beer, wine, swing top or kombucha bottles.

Product Features:

• Straw brush material nylon scrubber and steel handle
• Fits narrow, wide, tall and short bottles
• The easy clean, non scratching silicone bristles of our 12.5 inch 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
