Safe, non-abrasive deep cleaning - The clay scrubber safely adsorbs and lifts embedded contaminants such as industrial dust and bird droppings without eroding or damaging car paint or clear coat. Efficient metal powder removal - Uses water-based lubrication and controlled physical friction, with a nano-standard bonding mechanism, to target and remove persistent metal powder (eg brake dust) during routine car care. Repeated-use safety and performance - The triple-layer composite buffer keeps surfaces smooth and glossy, minimizes scratches or hairline marks, and controls friction intensity for safe repeated use on standard painted finishes. Comprehensive surface cleaning - Effectively tackles brake iron powder, tar spots, and sap remnants while addressing common finish contaminants for a complete detailing solution. Materials and compatibility - Clay scrubber for safe adsorption and lift on paint finishes; triple-layer buffer designed for repeated use on standard car surfaces; compatible with typical car paint and clear coats. 2-3 practical use scenarios - After highway driving through dusty or industrial areas, apply with light lubrication to lift metal powder and embedded dirt, then wipe clean for a refreshed finish. - Parked under trees or near sap-rich areas; use the clay scrubber to remove sap and tar without scratching, followed by the buffer to restore gloss. - Regular maintenance for a showroom-like finish: use the buffer during routine detailing to maintain smoothness, reduce micro-scratches, and preserve gloss over time.
