If using your gear in saltwater environments, you should rinse it off when your day is done as long as the product is waterproof. Salt water causes intense degradation of all metal parts. Removing screws can be difficult for repair technicians because they become corroded and must be drilled out. This corrosion also affects metal parts of the focus mechanisms and may cause difficulty in focusing by jamming up components that are needed for smooth focusing. Cleaning the body of your product is easy. You can use Simple Green (mixed with water) and a toothbrush to brush away the dirt. When finished, use a cloth or paper towel to dry the surface of the armor. The following pictures of a repair show where the binoculars were corroded by salt water. All photographs were taken by the author. Gail Fisher has always been an outdoor person and considers her birding gear so important not only to see birds, but all of what nature offers us. She has spent 25 years as a repair technician and the manager of the Swarovski Optiks repair department in Rhode Island.
