Lenspen's excellent activated carbon cleaner is always on top of the situation. Do you notice dirt on the surface of the optics? The surface must be dusted with the push-out brush, then by unscrewing the cap on the other end of the cleaner, the optics can be perfectly cleaned with the soft surface filled with activated carbon on the rubber cleaning head. Its use is safe, fast and simple. Another advantage of activated carbon cleaning is that it can be used without any time limit; no moisture, so no dripping or evaporation; and it can also be solved comfortably with one hand. The size and design of the cleaning head make Micropro suitable primarily for small surfaces, such as Optical viewfinders for SLR cameras, eyepieces for smaller binoculars, optics for telephones, etc.
