Dirt is an inevitable by-product of the areas you operate in. Any dirt on glass or plastic surfaces will scratch if carelessly wiped away. Using rags or clothing can ruin good equipment.
An Abbey Lens Cloth made from remarkably fine microfibers is soft and supple. Kept clean it will not harm expensive, delicate equipment. Used together with Abbey Lens Clean or Abbey Anti Fog Spray it is especially beneficial, in avoiding scratching of lens, scopes, visors and glasses.
