I love looking into this stuff, becauase we often realize we contradict ourselves or learn things that in practice don't apply.

Opticians will tell you to never clean with alcohol, but lens cleaners are mainly alcohol.

We use alcohol and yet it is often associated with AR coat removal because it is a solvent.

You say not to use Vodka. Well, it is distilled alcohol (like the water we're supposed to wash glasses with), but at the same time Ethanol, an alcohol that on my opinion is less aggressive than Isopropryl (I'll never understand how the US uses it instead of Ethyl) and Isopropyl is almost 100% pure hand wrecking alcohol.

Vodka is purer still. No desnaturant.

Remember to keep an eye on the rear element as well. Condensation can eventually leave a film on it so it looks clean but your photos start getting soft.

Post. Color. Gear.

Thanks for pointing out the pressure needed to damage the front element, Chris. I've told people that in the past. The glass on lenses isn't the same as some cheap window glass. It can take some beating and still not "crack".

Normal glass is harder than most steel, so generally if you're not actively trying to damage your lens with something like a kitchen utensil you should mostly be ok. But yeah, be careful with for example sand, because sand has silica, which is much harder than glass, hence why you can easily damage glass with sand.

Would love to see a video on different approaches to getting rid of lens fungus. I've seen people use UV (UV-A, UV-B, UV-C, or just natural sunlight) Isopropyl Alcohol, Hydrogen Peroxide and Ammonia. I've often wondered what the best options are when trying to preserve lens coatings.

Alcohol soaked cloth worked for me.

@Kraťas did you mixed water or just pure isopropyl alcohol?

Vinegar is acidic so probabbly not a good idea, but.. Clear alcohol vinegar?

Mirrorless cameras have lead to a huge growth in usage of vintage lenses, so I want to chime in and along with many other commenters ask for a video on vintage lens cleaning: oily aperture blades, oil on internal elements, oil that has solidified, and remove black paint around lens mounts are good topics. Fungus is probably not fixable, so that's just a mention.

Chris, great content. Thanks to the lenses for taking one for the team. One question I have is can you use “expired” lens cleaning solutions. I just found an old bottle of Zeiss lens cleaning solution when cleaning out my bag. Don’t know how old it is but if I were to guess maybe 5 to 10 years old. There’s no expiration date printed on any of most of these cleaners. So are the solutions still good to use?
