Sonax Gloss Shampoo Concentrate 1 L effectively penetrates and dissolves dirt while preserving the protective wax layer on paint. It safely cleans paint, rubber, plastic, vinyl, and glass surfaces with gentle, phosphate-free surfactants. For best results, remove coarse dirt with water, dilute 2 caps in 10 liters of warm water, wash from top to bottom using a multisponge, then rinse thoroughly to avoid residue or water stains. Ideal for maintaining a glossy, clean finish.
