Yes, I'm angry too. It's hard to get the help we desperately need.

Sorry but I can't read that small print on my computer. I usually have

to print everything out and even then it's hard for me to read.

Jeanine. People have questioned whether toxins can be removed from

glass, and so this addresses one issue, removing fungus from glass. I

wouldn't have thought it would be difficult but reading this, apparently

it is:

Fungus in optical instruments.

Many old optical instruments have fungus growth on a glass surface.

Fungus

does not look like haze but has an appearance like hairs or tendrils

branching

from a center. While the fungus can be removed by cleaning, it

frequently has

etched the glass, since fungi secrete enzymes and acids to chemically

alter their

environment so they can absorb nutrients. This etching requires

repolishing,

which if done unprofessionally will ruin the instrument. It is not

possible to

tell if the glass is etched until the fungus is cleaned. Maintenance of

optical

instruments involves prevention of future fungus problems, especially if

located

in damp regions.

To sum up the lengthy documentation below:

--WWII research programs on fungus in optical instruments (,

below) used

sodium ethylmercurithiosalicylate, now known as Thimerosal and widely

used

consumer medical products. When mixed in paint used inside the

binocular, this

was found effective at preventing fungus. It is not known if Thimerosal

is so

used today.

--Hydrogen peroxide, or bleach, can be used to kill fungus.

--Leitz documents describe a fungus treatment of 94% distilled water,

4% clear

ammonia (for cleansing) and 2% hydrogen peroxide (to kill fungus).

--Carl Zeiss Oberkochen, dept. KuDi, sells: Fungus Cleaning Agent

" Fungusreiniger NEU " . Dilute with ethyl alchohol, leave on glass for

one hour or

more, then clean. Not poisonous but avoid contact with skin. 100ml

bottle, INR

0117.362 500ml bottle, INR 0117.361 1000ml bottle, INR 0117.360

--Notes on treatment & prevention are found at the end of this text.

(It's rather long, so I will send rest to you directly, rather than post

here.)

yes, very much worth reading, thanks for enlargeing and sending to

me. also very interesting how in the 40's they knew enough to be

conserned about fungal toxicity/poisoning. wonder if men were getting

fungal infections in their eyes from useing these contaminated

bonoculars, even possably illness from breathing spores/myco's with

them being so close to the nose. a lot of research for something

thats not supposed to harm us.

amazeing, fungi etches glass but it can't possably hurt our insides.
