For years I had used lens paper or a Kimwipe moistened with a splash of
xylene, then becoming more safety conscious, I turned to a 50/50 dilution of
Windex which also worked to remove sythetic oil from the precious
microscopic lenses. We have all heard of the horrors of using alcohols or
acetone as a lens cleaner - which eventually softens and dissolves the
cement that holds the lenses in place. Acetone can also remove the paint
from the microscope.

I now use a commercial mist called ROR lens cleaner (Residual Oil Remover).
Use it on my Hasselblad as well. I also remove and store clean lenses in a
zip lock baggie when not in use.

Hello histonetters,

Just wondering if anyone has a favorite method of cleaning their oil
immersion lenses for light microscopy.  Commercial products versus
We are re-evaluating some of the procedures in the medical student
laboratory and this is one of the areas of concern.

Many thanks,
