For car bodies that have accumulated micro-scratches and wash marks, Kärcher’s RM 660 Polish offers a 2-in-1 action: it removes fine scratches—especially those left by car wash brushes—while applying a long-lasting, weather-resistant protective layer in a single step. Its microplastic-free formula contains special care components that accelerate drying, restore original shine without holograms, and activate a beading effect against water and dirt. Ready to use, it is applied manually with a sponge or soft cloth to clean, dry painted surfaces. Note: not suitable for matte paints or heated surfaces.
