Baader Planetarium's Optical Wonder Fluid is the finest lens cleaner we have found. It is especially good at removing fatty contaminants from fingerprints, eyelashes and most pollens. It also removes bacteria and fungi that can harm optical coatings and prevents their return.
The Baader micro-fibre cleaning cloth is made from a finer grade of micro-fibre than the typical lens cloths sold at camera shops or opticians.
Available separately but when used together (place the fluid then the cloth in your cart) they make a remarkably effective and safe cleaning product.
Note: Baader Optical Wonder is primarily a lens cleaner, it is not suitable for cleaning Newtonian mirrors.
