The OXO Good Grips Deep Clean Brush Set features two tools for scrubbing those hard-to-reach places. Both Brushes include sturdy nylon bristles and comfortable non-slip grips. The Large Brush is sized and angled for cleaning grout, shower-door tracks and more. A soft thumb pad on the back of the head allows for optimal comfort while applying maximum force. The Small Brush features a compact bristle head and pointed profile, great for cleaning in and around fixtures, thin grout lines and other tight spaces. The Small Brush also includes a built-in Wiper Blade for removing grime inside drains and other crevices.
