Kärcher RM 623 Stone and Facade Cleaning Agent, 5 liters

The Kärcher RM 623 Stone and Facade Cleaner, 5 L, is a liquid detergent for use with high-pressure washers on exterior building surfaces. It removes built-up oil, grease, soot, and atmospheric dust. The 5 L container provides enough detergent for several residential or light commercial cleaning jobs and is suitable for use on stone walls, terraces, and building facades. The concentrated formula breaks down ingrained grime that water pressure alone cannot shift from hard surfaces and is designed to revive stone surfaces that have darkened over time from atmospheric soiling.

The solution is safe for use on stone and aluminium and will not damage these surfaces during cleaning. The formulation is ASF-compliant, making it suitable for drainage systems fitted with oil separators. It leaves a fresh scent on treated areas once cleaning is complete. At 140 mm wide and 190 mm deep, the container sits steadily on shelves and in storage areas. Each full 5 L bottle weighs 5250 g, making it easy to carry between storage and the cleaning site.
