LEWI chamois leather for clean windows and surfaces, without streaks and stains. No other cleaning agent than water is needed for normally polluted windows. LEWI chamois leathers are natural products environmentally friendly, skin-compatible, actively absorbing, easy-care and antistatic. This is what makes them so popular among cleaning professionals. The Lehmann KG has more than 100 years of experience in producing different kinds of leathers. All chamois leathers are continuously tested and checked. They are made of pure sheep skin and extensively finished in many separate working steps. Only chamois leathers that really pass all tests and meet all examination requirements get our quality seal as a sign of proven Lehmann quality.
