Binocular and scope glass picks up dust, rain spots and finger marks on every outing. This six-piece kit deals with all three, and packs down small enough to live in a jacket pocket or a harness.

• Air blower, to lift grit off the coating before anything touches it
• Double-ended lens pen: retractable brush at one end, carbon cleaning tip at the other
• Soft dusting brush for barrels, hinges and eyecups
• Refillable spray bottle, supplied empty
• Microfibre cloth
• Drawstring pouch to keep it all together

Suitable for binoculars, spotting scopes, rangefinders and spectacles.

Blow the loose grit off first. Dragging a cloth across a dry, dusty coating is what puts the fine scratches in.
