I have a cloudy Elmar. It produces some good images but I am sure the cloud or fog inside is reducing the contrast a little bit. I want to clean off this fog without even opening it.
Is there any solution? I have been reading about Ammonia and Peroxide solution. But I don't understand how to make this solution and use it for the cleaning process. Do I have to immerse the whole lens in the solution? Please help.
Also how do I get peroxide? Home depot? I am aware that Ammonia is the Windex that I use for cleaning my car's glass. How do I get peroxide. Any clue?

See the foggy part?
I don't know how to clean that without dismantling the lens. Or there's no way!

no way! Mix is dangerous to you and lens both , it's kill fungus well , but also makes boiling mixture when fresh. Lens is cheap Leica, low contrast lens with little respect. Cleaning not helps.

Yes. Agreed.
Here in USA also called sometimes "drugstore" . . . . . or "pharmacy".
(hydrogen) Peroxide is sold "over the counter" routinely. It is not a prescription item so you will not need to speak with a pharmacist in person. It's somewhere in the aisles of your CVS, or Rite-Aid, or Walgreens, or whatever drugstores you have in Florida. Hydrogen peroxide is a powerful germicide, bleach, you name it. And as Attila says, used improperly it can yield up unwanted outcomes. Be really careful.
One final thing: hydrogen peroxide deteriorates, it break down, pretty readily. Keep it away from heat and sun. Store it in a cool, dark place for longest life. |

The lens must be dismantled to clean glass surfaces inside. 
Tip: use the mildest cleaning solution that works. Try the mildest, say distilled water. If that doesn't work, try ethanol. If that doesn't work try naptha. Then cold cream. Tiny drop of acetone on an earbud. I.e. progressive increase in cleaning power rather than full blast, which may do some damage.
