As per the ETC Source Four manual you should use a diluted mixture of ammonia and water. Ideally you should use a lint free cloth, but paper towels are OK. This is OK to use on any lenses, but make sure you do it in a properly ventilated area, ammonia fumes are BAD.What do you use to clean lenses?
See this thread. I recommend only distilled water and a lint-free cloth.
Attached below are excerpts from two ETC documents, appearing to give conflicting information regarding ammonia. The first (FAQ) is dated 2001 and the other (Assembly Guide), 2007. Both documents say NOT to use ammonia on the reflectors.
Once again, it appears we need guidance from the factory.
The First says that. The Second, newer, discussing S4 ERS glass lenses only, says "Isopropyl alcohol, distilled water, or a 50%-50% mixture of each can be used to clean the glass surface." Again, this is for SourceFour™ ERS lenses only.It says to use alcohol on the reflector and ammonia on the lenses.
Yes, but one would hope your lenses don't have anything thicker than ketchup on them! But I'm bothered by the fact that your dishwasher leaves spots on everything. If you have to "de-spot" 200 sets of lenses, you'd be better off using 50/50 rubbing alcohol and distilled water and doing them by hand. The S4-PAR lenses I would run through the dishwasher, as spots won't affect them much, if at all, optically....plates with anything thicker than ketchup on them always need to go through more than once.
Cotton baby diapers work well. If it was good enough for Ferris Bueller's best friend's (Cameron:Alan Ruck) father to rub his Ferrari......Don't forget the part about the soft, lint-free cloth...
