For best results when using ZEISS AntiFOG Kit, the lenses should first be cleaned using a regular lens spray to remove any excess dirt/grime on the lenses. Once the lenses are completed dry, spray both sides of the lens with the AntiFOG Spray. Next, rub the AntiFOG Cloth evenly and generously on both sides until the surface is completely dry. The thin layer of coating should last for up to 72 hours. You should repeat this application process as the effects begin to reduce with time.
