RTC Trowel Cleaning Brush — Clean Tools Lay Clean Notches A trowel with dried thinset packed in the notches spreads uneven ridges, and uneven ridges mean uneven coverage under the tile. The RTC Trowel Cleaning Brush has bristles stiff enough to chew through dried thinset yet resilient enough to hold their shape scrub after scrub — so your notch profiles stay precise and your coverage stays consistent. An ergonomic grip gives you leverage on stubborn buildup, and it's compact enough to stow in a pocket, bucket, or at the mixing station. Keep it next to your Comfort Grip trowel and Stumpy Joe so a clean edge is always a few strokes away.
