Apply a commercial limescale remover

Apply a CLR-type limescale remover to affected fixtures following the manufacturer's instructions for application method and dwell time. Scrub with a sponge or brush if needed and rinse thoroughly with water. These products handle heavy, long-standing deposits that household acids struggle with.

Why It Works

Commercial removers contain stronger acids — typically phosphoric or hydrochloric — formulated to dissolve heavy calcium carbonate buildup quickly and completely. They are designed for speed and effectiveness on severe limescale.

Tips

• Always ventilate the area, wear gloves, and use protective eyewear
• Never mix with bleach or other cleaning products — dangerous fumes can result
• Do not use on natural stone (marble, granite, travertine) as the acid causes permanent etching
• Rinse fixtures thoroughly after use to prevent acid from damaging chrome or other finishes
