FAQs

• When I touch the lens pen with my finger, the finger is marked in black. Does the black colour have any effects on the lens when it is cleaned?
  The lens pen has been designed for being used on a lens and therefore leaves traces on other materials. The carbon cleaning tip is immediately ready for use and allows you to clean all optical surfaces quickly, gently and thoroughly.
  
  It is important that you remove the dirt with the lens pen in short circular movements from the inside to the outside of the lens. By doing so, the dirt is dissolved and absorbed by the pad.
  
  Please note the following when using the lens pen again: Put on the cap again, a rotary movement activates the chemical compound once again so that the lens pen can be used for about 50 to 100 times depending on the degree of soiling. Afterwards it should be replaced. Laboratory tests have shown that the lens pen cleans lenses much more gently than conventional cleaning systems.
  
  If you use the lens pen as described, you will get a clean filter/lens glass.
