Binoculars, like other optical devices, are a sensitive piece of optical equipment. Regular maintenance and tunings are important to look after the basic mechanics of your optics and keep grit away from the lenses. Following our basic maintenance instructions will ensure you have good use out of your binoculars for many years to come.

Basic Self Maintenance of Binoculars & Optics

The first and simplest step for taking care of your binoculars is to always store them in a case that is clean and free of dirt/grit. This will help to protect and preserve the optics. Add a small sachet of desiccant (silica gel) to help remove any humidity or moisture as optics and moisture don’t mix. Long term exposure to moisture will lead to degeneration of coatings, fungal growth and an array of other issues.

When cleaning binoculars always blow on the lenses lightly or use an air puffer. Once any dirt or grit has been removed you can clean the surface with a clean, lint free, cloth.

Once you have removed any dirt or grit on the lens surface apply a small amount of Isopropanol (lens cleaning fluid) and with a gentle circular motion clean the lens. There are a wide range of lens cleaning products on the market. Check first to see if they are suitable for multicoated lenses. Do not continually rub the surface as this can cause damage to the coating. Once the coating is damaged then the refractive order of the lens changes (light scatter)… So always be gently when cleaning lens surfaces.

It is advisable to also remove any dirt or marks on the outside of the body of the binocular as over time this will cause deterioration of any protective covering around the body. Our hands have a tendency to sweat when holding a binocular and this will lead to the rubber armoured coating lifting away from the body if not properly addressed.

The hinge system on binoculars often collects dirt so gentle cleaning of the hinge mechanism is also recommended. A gentle blow with an air puffer/brush is a good idea then a gentle wipe with a cloth (not the same one you use for cleaning the lenses). The grease invariably becomes hard over time so a small amount of silicone oil to free up the hinge sometimes helps.
