TOOLS AND MATERIALS

A bright light for examining the lens before and after cleaning.

A cloth and cotton buds for cleaning the outside of the binoculars and the inside of the lens caps.

A puffer and lens brush for removing loose dust and debris.

Lens tissue (kept clean in a ziplock bag) for doing the bulk of the optical cleaning; if you don’t have lens tissue, a viable alternative is a very clean microfibre cloth.

Lens-cleaning fluid or isopropyl alcohol for marks that won’t puff or brush off.

A lens pen for cleaning off accidental fingerprints or water marks when you’re observing in the field.
