The OXO Good Grips Water Bottle Cleaning Set includes a Long Bottle Brush, Straw Brush and Detail Cleaner, to provide a thorough clean for any of your drinking buddies. The Long Bottle Brush is perfect for cleaning the inside of bottles – even those with narrow necks. The Brush features soft side bristles to clean bottle walls without scratching and short, firm bristles to thoroughly clean the bottom of bottles. For those hard-to-reach places, the Straw Brush easily gets inside sports bottle straws and the Detail Cleaner gets into the crevices of caps and lids. All three tools store together on a handy ring and easily snap off for use. The Brushes have durable nylon bristles that won't lose their shape and soft, comfortable, non-slip handles.
