Product Information
HMK® P324 Liquid Stone Soap is a concentrated, 100% natural, pH-neutral stone cleaner and conditioner for routine interior maintenance. Designed for natural stone, cast stone, agglomerate, artificial stone, ceramic tile, and other compatible tiled surfaces, it provides dependable cleaning across all surface finishes.
With regular use, this stone soap develops a clear, invisible, dirt-repellent film that helps impregnators and penetrating sealers resist stains. The conditioning layer maintains a natural appearance while gradually enriching the stone’s color, allowing surfaces to look cleaner and more vibrant without a visible coating.
The concentrated formula provides efficient maintenance for residential and commercial interiors. Its protective solution is intentionally left on the surface rather than rinsed away, reducing cleaning steps while allowing the dirt-repellent conditioning film to develop with continued use.
