How it works Attach the brush head to the chuck of your electric drill, tighten, and use the drill at low to medium speed to scrub stubborn dirt, soap scum, mold, or grime. Change brush size to match the cleaning area for faster, deeper results. Suitable applications and use scenarios Shower and bathtub cleaning: remove soap scum and mildew from walls and corners without aggressive scraping. Tile and grout restoration: scrub grout lines and textured tiles to reduce buildup and improve appearance. Bathroom fixtures and porcelain: clean sinks, toilets, and porcelain surfaces to remove stains and mineral deposits. Other uses: kitchen floors, patios, or any surface where powered scrubbing is helpful. Usage tips Start at low drill speed and increase gradually as needed to avoid splashing or surface damage. Test on a small inconspicuous area first to confirm suitability for the surface. Use appropriate cleaning solution for the material being cleaned and rinse thoroughly after scrubbing. Package notes Includes 4 brush heads: 2inch, 3.5inch, 4inch, 5inch. Please allow slight measurement variation due to manual measurement.
