Bleach is safe to kill fungus on the lens.
But, it affects the coating?

I am unsure , but I think all cleaning technics effect coating especially if coating is soft. If need I use strongest chemical what I have and not care much about coating.

I think the cleaning and destroying of the fungus on the glass surface is not the problem. The spores somewhere in the lens could probably with bad enviroment cause a bit faster new fungus.
But the main problem for my fungus cleaning is, how I could clean the marks on the surface which could not easily be wipped away. If they are removable at all. Suppose mostly not - destroyed surface. _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html

Fungus is very strong creature it can survive almost everything and grow again if their is humid, dark environment. I saw fungus in Nuclear Power Plant at dark , humid places in intensive radioactive environment. I don't know vinegar does only current clean only or give a resistance for surface for long term. Strong chemical make it's protein to liquid stage no chance to survive. |

No, there is no need to dilute it.
I must say that I never cleaned a fungized lens. I only know that ethanol or isopropanol can be savely used to kill fungus and to clean glass surfaces.
Problems may arise if there are cemented elements. Be careful here.
There are many different kinds of fungus and it is possible that an aggressive fungus itself has already damaged the lens coating, as ZoneV suggests. _________________ Best wishes, Wieland

I wouldn't use these.
I suspect that they can react with the coating and/or glass.
I would use organic solvents like ethanol. _________________ Best wishes, Wieland

Ammonia can remove coating even in only one application of it.
I even have a personal experience with Windex(contains ammonia) and coatings.
Around 1997 I bought my first Professional and expensive 17 inch CRT monitor a Sony 200PST. This monitor had a anti-reflective coating on the glass. Out of stupidity I tried Windex to clean it having NOT read the manual .
Exactly 15 sec after applying with a micro-fiber super soft cloth , the coating of the monitor started to peal off!!!
I had to rub off all the coating because it just looked awful _________________ Canon EOS 5D MkII , EOS 50E, Contax RTS, Olympus OM2n, Nikon Z6ii

Perhaps Hidrogen-peroxid+ammonia is comes out as new material . I clean all my lenses with this mixture without any coating trouble. It is clean effectively dirt, fungus etc. I extensively use it ot remove fingerprint dusts from lens surface. _________________ -------------------------------

Attila ,
I did a quick search on the net using the words coating lens and ammonia and I got this:
Carl Zeiss Optical Inc Lens Spray Cleaner ammonia free, safe for multi-coated lenses ...hmmm
I also got this :
Quote: |
It's also said that some early coatings don't adhere to the glass as well as modern coatings and can also be attacked by cleaning fluids containing ammonia (like Windex), so that's another factor to bear in mind when working with coated optics made before the 1960s |
from bobatkins.com
And this from Zeiss.com:
Quote: |
Most antireflection
coatings are composed of layers of magnesium fluoride
and should only be cleaned with agents free from ammonia
and acids.
Sometimes, household glass cleaning agents (e.g., SIDOLIN,
SPARKLE, Blue WINDEX) are recommended. However,
as they contain diluted ammonia, they should not be used
routinely. |
Quote: |
Never use acids or ammonia to clean objective front lenses,
which are sensitive to acid and alkaline vapors. |

Just a thought ...
I found this:
LAMISIL anti-fungus spay that contains:
1% terinafine hydrochloride and consists of Purified Water,ethanol(23.5%w/w),propylen glycol and cetomacrogol 1000 .
This product also exists in gel form. I don't know if it affects coating but it's a very known and strong anti-fungal medicine for human skin and from the label I don't see anything acidic or bad. Hmmm
Also a known foot nail fungus treatment consists of 50%Hydrogen peroxide+50% Apple vinegar.
The Hydrogen peroxide seems safe for the coating but not the Vinegar... _________________ Canon EOS 5D MkII , EOS 50E, Contax RTS, Olympus OM2n, Nikon Z6ii

... Also a known foot nail fungus treatment consists of 50%Hydrogen peroxide+50% Apple vinegar.
The Hydrogen peroxide seems safe for the coating but not the Vinegar... |
Please note!: the treatment formula is 1/2 Hydrogen Peroxide (3%) and 1/2 Apple Cider Vinegar.
Hydrogen Peroxide used should be a 3% dilution, as commonly available at chemist/pharmacy. 3% hydrogen is safe to use on lenses. Stronger than 3% industrial hydrogen peroxide is a safety hazard, causes severe burns, might attack metals in coatings, those metals that can be oxidized, if any. _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

I use distilled white vinegar. It is mild, doesn't affect the coatings and removes and kills the fungus.
Distilled water can then be used to remove the residual vinegar. |
