Sometimes all you need is a third hand! This handy brush suction cups to the sink bottom and stays there so you can safely wash glassware, mugs, or jars. The bristles are sturdy yet soft so your cleaning is thorough without scratching. This brush is also handy for anyone doing dishes with limited motion due to a stroke or other health issues. Standing at 6.5" (16cm), it easily washes glasses 5.5" (14cm) tall. Plastic, silicon and we recommend hand washing.
