Acid-based bathroom cleaner

This 32 fl oz professional-grade formula dissolves soap scum, calcium, limescale, and rust stains on contact. The acidic no-scrub solution is ready to use straight from the bottle for shower, tub, and tile surfaces. It targets tough water-related buildup without leaving residue behind. Trusted by professionals for over 85 years of formulation expertise.

Sustained stain removal performance

The acidic chemistry continues breaking down mineral deposits and organic buildup during the dwell time rather than relying on a quick surface wipe. Foaming action clings to vertical surfaces to maintain contact with stubborn stains longer. It penetrates deep into grout lines and porous tile to lift embedded dirt and rust discoloration. Results improve on heavily scaled areas with repeated application cycles.

Simple spray-and-wait installation

Application requires only spraying the affected area and allowing the formula to work before rinsing, with no mixing or dilution steps. The main issue arises when used on acid-sensitive materials such as natural stone, brass fixtures, or coloured grout where etching or discoloration can occur. Proper ventilation is necessary due to the acidic vapours released during use. Always test a small hidden area first to confirm surface compatibility.
