Actually I am surprised a Zeiss person told you to use glass cleaner---it's
usually Nikon people.
 
I personally find that especially with oil objectives used on inverted
microscopes (therefore the oil has to be the thicker kind) the glass cleaner
stuff is a joke.  It just doesn't cut through.  It's why I use organic
solvents.  
 
Zeiss chemical coatings can withstand chloroform;  Nikon lenses don't have
such robust coatings and that's why they recommend Sparkle. (the purple
glass cleaner).  But I always get irritated when they say that because as I
said, glass cleaner and ethanol just does not make a dent.

A Zeiss person once told me to use:

Windex (or other clear glass cleaner) 50%
70% alcohol 50%

It always worked well for me.

       At the moment I'm still using ether to clean my microscope
objectives. For health and safety I'd like to move away to some other
cleaning agent. What's everyone else using?
