Cleaning your racks: To clean racks and to extend anti-fog, anti-static & dust repellent properties use acrylic cleaner, we recommend Brillianze or Novus available at home improvement stores. If acrylic cleaner is not available then simply use mild alcohol free soapy water and use same process. Use a micro-soft or 100% cotton cloth. Spray evenly, rub gently & before surface dries, polish with dry cloth. Do not use alcohol based cleaners such as Windex. To remove fine scratches that may occur over time use acrylic scratch remover such as Novus#2. Just as you would treat nice sunglass lenses, never clean when dry.
