Fungus Removal

I have heard that equal parts Hydrogen Peroxide and Ammonia is good for Fungus removal in old lenses but can't find what sort ... Hydrogen Peroxide seems to come in a 3% health grade solution and a 35% food grade solution, didnt see any 100% solution.

Ammonia is a gas so not sure what solution they are talking, Cloudy Ammonia?

what is the go that is not going to affect Pentax lens coatings??
