Ethanol on its own may not be the best choice in treating a fungal surface contaminated lens, since it has very little effect on the fungus.Indeed it may actually stimulate further cell growth. Zeiss does however recommend diluting its own cleaner in ethanol.
The advice from Leitz is to use a 50/50 mix of hydrogen peroxide and ammonia in distilled water, and from my experience, is both the most efficacious and least harmful.
Avoid purchasing hydrogen peroxide in quantity, otherwise you will become a person of interest to the security services


Noted! Thanks.
