Threeinone corner cleaning brush engineered for precise cleaning of wall corners and narrow gaps. The tool combines a cornerfocused head, a side brush for fine gaps, and mixedstiffness bristles to balance scrubbing power with surface care. Key benefits Cleans corners and gaps more effectively than a flat sponge or cloth by targeting hardtoreach angles. Mixed bristle stiffness (moderately soft and hard) provides firm scrubbing where needed while minimizing surface damage. Streamlined, curved handle improves reach and wrist control for steady, accurate cleaning in tight areas. Features and compatibility Threeinone design: corner cleaning head plus an integrated side brush for narrow gaps and crevices. Bristles: moderately soft and hard to handle dust, grime, and residue without excessive abrasion. Handle: streamlined, curved shape for ergonomic handheld use and better access to or low corners. Suitable for use on walls, baseboards, grout lines, window and door tracks, appliance edges, and other narrow or angled spaces. Performance notes Designed to dislodge and lift dirt from corners and gaps that are difficult to reach with standard brushes. Balanced bristle stiffness gives effective cleaning while helping protect typical interior surfaces from scratching. Typical use cases Kitchen: remove grease and crumbs from backsplash corners, stove edges, and appliance seams. Bathroom: clean tile grout lines, shower corners, and around fixtures where dirt accumulates. Home maintenance: clear dust from window tracks, doorframe grooves, baseboard crevices, and air vent edges.
