About ten or twelve years ago I received a small pair of binoculars, Nikon’s Sprint II 9x21, as a gift. They were purchased from a reputable optical supply house in the States. The body of the binoculars is made of two kinds of synthetic materials, one green, not unlike plastic, and the other black, more like rubber. After a few years in storage (room temperature), the green portion has become mildly tacky to the touch. The other part of the body, however, is extremely sticky and stains anything black that comes into contact with it. Is there any way to stop what seems to be a deterioration process occurring here?
