The most advanced, plant-based dry cleaning system in the world — safer for your garments, safer for your family, safer for the planet.
Kreussler — Germany
What is SYSTEMK4?
SYSTEMK4 is a revolutionary dry cleaning system developed by Kreussler, a German chemical company with over 150 years of expertise. It uses SOLVON K4 — a biodegradable, plant-derived solvent — as a complete replacement for the traditional PERC (perchloroethylene) chemical used in conventional dry cleaning.
Unlike PERC, which is classified as a probable human carcinogen by the EPA, SOLVON K4 is non-toxic, biodegradable, and leaves no harmful residues on your garments. It is the gold standard in modern, responsible dry cleaning.
