Zep-O-Shine is a premium-grade, concentrated car wash. The one-step wash-and-shine is ideally suited for hand-washing applications at car washes, detailing shops, service stations, car and truck leasing centers and new and used car dealers. The product contains a high concentration of synthetic detergents, wetting agents, foam stabilizers and water softeners, and all surfactants used are biodegradable. It effectively cuts through even the most stubborn of soils, leaving behind a waxed, shiny like-new surface. It also contains a new polymer wax emulsion which weatherproofs and leaves a glossy finish on the car. After drying, gently rub with a towel for an even glossier sheen.
