Hi anybody knows of a good cleaning solution to clean a Prism source.
The guide book recommends a solution of nitric and hydrofluoric
acid.....I would like to keep away from HF if I can.
A colleague from England recommended something called "Ferrotone".  I
tried to find a supplier in the web, but alas! when I type ferrotone on
a search engine, I get web pages related to pet ferret vitamins!  I am
sure thats not what he meant.  Thanks. Leo.
