Remove Internal Binocular Fogging

Internal fogging can be fixed easily if you know what to do.


Internal fogging can be a serious headache for birdwatchers, or anyone else who uses binoculars. Fogging on the inside of the binoculars interferes with the viewing, and can't be easily wiped away like external fogging can. The moisture on the inside of the binoculars that causes fogging can also damage the binoculars, by promoting the growth of fungus inside them. Fortunately, the treatment of internal fogging is a fairly simple procedure, though it requires patience.


Instructions


1. Leave the binoculars in a warm dry place for several days. Most binoculars are not airtight, so any moisture inside the binoculars should evaporate into the drier air outside.


2. Seal the binoculars inside an airtight plastic bag along with some commercial desiccant. The desiccant will absorb the excess moisture, eliminating the source of the fogging.


3. Keep the binoculars as dry as possible on future outings, once the moisture has been removed. If you are using the binoculars during wet weather, keep them covered when you are not looking through them. Wipe off any outside moisture as soon as possible.
