Lens Cleaning Solution

When you are not able to dust off the lens with a manual puffer and the chamois with distilled water will not work try the following mixture.

This glass cleaner recipe calls for 1/2 cup soapy ammonia, 1 pint of rubbing alcohol and 13 1/2 cups of water to make one gallon. Since I’m not privy to making more than what I need (who needs extra containers laying around?), I cut down the recipe for a 32 oz. Windex bottle – a fourth of a gallon. Here are the new measured amounts:

· 1/8 cup (1 oz) soapy ammonia

· 1/2 cup (4 oz) ethanol or rubbing alcohol

· 3 1/3 cups water

Soapy ammonia is basically 4 parts water, 1 part ammonia and a “squirt” of dish soap. In doing the math, here is my cut down recipe for what I will need to make soapy ammonia for a 26 – 32 oz. size bottle:

· 5 teaspoons water

· 2 teaspoons ammonia

· 1 teaspoon dish soap

This will make a bit more than 1/8 cup, but I’m trying to keep things simple. None of us want to remember half measurements!

Spray it on and use lens paper for cleaning. Not Kleenex or Kim wipes or paper towels or your shirt tail or etc.

I've used this successfully on coated optics, primarily Zeiss and Schott.

Works well on eye glasses although unless you specifically request glass you receive plastic lenses. Regardless though, no damage to the plastic lenses as experienced using pure ethanol.
