    Jst a tip for putting lens back to the mount: before you get it out, place a mark on it with a sharpie, then mark the case too. This will help you to determine the original ANGLE of the lens(matters when it comes to image corrected lenses) But the most important part: It is not advised to just pop back the lens. It may get damaged/chipped by the falling. Instead, hold it like a waiter holds a plate, with your fingers on the front of the lens and turn the assembly upside down, elevate the lens inside the assembly from below. This ensures that the lens won't get stuck in the mount and you don't have to use pressure on it.
    Also it is best to not rub the lens with bare hands. Instead pour water and some soap in a small container and let the lens sit in it for two days. All the fungus will be gone. Calcified containments will get loose and fall off. This is less harsh for the coating than the acidic treatment.
    Hope this helps in future lens cleaning.

      Fungus spores go everywhere. If they are on the lens then the entire tube should be cleaned before reassembly. It’s just like a loaf of bread: once you can see the mold you can be sure that the spores are spread all over the loaf and you should just throw the whole thing out.

    Some other hints:
    1) Store lenses UPRIGHT and away from excessive heat. This keeps the lubrication from melting into the aperture blades.
    2) Buy a bag of Silica white crystal CAT Litter. It's CHEAP DESICCANT!!!!! Place it in nylon stockings or orphan socks and tie them off in a knot. Place them in the containers with your lenses...stored upright:-) Recharge the desiccant every year by drying at low temp in the oven or in hot sunlight.

    Be careful with distilled vinegar! Especially with old lenses. I tried on mine and it etched away surface together with coating! Lens element is now of milk color. Use only non acidic sollutions (like kitchen mold killer), they kill and remove mold as well and you dont risk the glass being damaged.

    I bought a FD 50mm 1.8 a few weeks ago from a thrift store. First time I ever bought an old manual lens and I had no idea how to test the aperture (these stay open until you actually take a photo and only close on the body). So I just bought it. It was only $20 with a AR-1 Program. When I got home and started looking more into it i realized that my aperture blades were stuck.
    I read online you can first try to pour isopropyl down into the camera and move the blades alot and eventually it'll work... Which it did. However some isopropyl went between the lens elements and was stuck. It wasn't evaporating for at least 3 days, was just pooled up on the lenses (both front and rear elements were like this).
    So I decided to take it apart, only $20 and I figured if it doesn't work I can just sell the camera body and make my money back anyway. It took awhile to figure out how to dismantle the elements, especially the rear... Took a few days to figure out how to even get to it. But once I got to them it was easy as pie to clean up. Just a bit of isopropyl few puffs of air made sure it was nice and dry dust free.
    I also took apart the focusing mechanism. Now THAT was difficult to put back together. But I tested it last week and everything is working fine. I have a bit of dust in the front element but nothing you that'll affect image quality.

    Some fungi will etch coatings after awhile, so a cleaning will not reverse the damage. Also, you should be more sensitive to damage on the rear elements of the lens. Sometimes, edge fungus damage or even spots on the front glass will have little to no effect on image quality. However, the minute you move further back toward the other lens elements the more impact even minor damage can have on image quality. IMO.
    If I know a lens only has damage to one element but the rest is VVG or better, I might opt to find a second twin in really bad shape at a very low cost...just to replace that one bad element. I did this once while looking for a front element on a Vivitar 28mm.

    Most of the time the fungus spores don't pose any real issues when taking a photo in terms of picture result but if you live in a humid environment, better try and get rid of it to prevent it from spreading.
    Sometimes the fungus spores will actually etch itself into the glass leaving fine scaring.

    For fungus removal I use hand cream also called "cold cream". It`s amazing. There is no risk involved by using this method, since there are dangerous acids that might eat into the lens or coating, nor do you have to "scrape" the fungus with it. After the treatment I use luke-warm water to get it off. The final stage is isopropil alcohol to remove any grease and other residue and then I use distilled water for the final clean up. I use ether Q-tips or microfiber lens cloths. Do not use paper towels.

    The best way to deal with fungus is to PREVENT their colonization. Its moisture that predispose their growth. I live in South California and not a single local lens, even if 100 years old, has fungus as we don't have moisture or humidity. On the other hand invariable I see these fungi colonies on almost every old lens that comes from a humid location, say India or some European countries. So my best advise is to avoid moisture/humidity. Try to pack / store you lens along with dehumidifier package (Silica Gel Desiccants) and don't store you lenses directly when coming from a wet environment, prior to a full dry up. If you have the opportunity of exposing your lens to UV light, every now and then, that is another good solution especially for those living in susceptible environment to stop further growth of small microscopic fungus colony, before they become visible to eye.

    • @Bytesmiths

      I agree with the prevention part!
      I once had a lens that got totally destroyed by fungus, because I used it skiing, and kept it in the damp pack between ski outings. Yuk.
      Now living in the Pacific Northwest, I was determined not to let that happen again. I bought an Ikea "Billy" bookcase, with the optional glass shelves and glass doors. I got four halogen under-cabinet lights, mounted two on the top and two on the middle shelf, and removed the glass covers that say, "WARNING! USE COVER GLASS FOR UV PROTECTION!" It is important to use the HALOGEN bulbs, NOT LEDs. And whenever I buy something that has packets of silica gel in them, I sprinkle them around on the various shelves.
      I put sticky-backed foam weather sealing where the doors contacted the book case, EXCEPT along the top, so warm, humid air, warmed by the halogen lights, could convect out the top.
      End result: after a lot of use in humid environments (skiing, ice climbing, shooting waterfalls, etc.), I have no fungus or haze after nearly thirty years. (Of course, I make sure lenses go back in the cabinet with the lights on after being exposed to humidity.)
      There are expensive, ready-made solutions like this, but if you're handy, you can save a bundle by rolling your own.
      Also worth adding
 if you're tempted to buy a "bargain" fungus'd lens, keep in mind that if it has fungus, it was probably improperly stored, and may have other problems lurking, like metal corrosion.

    Your vid' is pretty much the way I do it except I rinse off with sprayed distilled water and drench with isopropyl-alcohol let to drain itself off vertically onto, say, a kitchen tissue (without recourse to lens tissues) which should leave no trace of fluid or residue. I also recall a maxim from my days as an astro mirror maker that if a glass can take and hold a breath upon its surface - i.e. fog it - it isn't clean. Which is an ideal that is difficult to achieve but can be done.
    I've enjoyed the few I've watched of your videos, and your imaginative new uses for beautiful old lenses. Particularly the 136 yr old brass lens vid' you shot, which I watched today - spectacular. Well done!

    Two comments: Hydrogen peroxide and ammonia mixed 1:1 will remove very stubborn fungus (but be sure to ventilate your work area as the stink is pretty bad). Place a rubber or plastic dish mat in your sink before handling a lens element, because one day you WILL drop the element and it WILL get chipped when it hits the metal drain.

      Personally, I never bother with a commodity lens like a {in your case Canon} 55-200 IS or a 50mm STM, I just buy another one. They are pretty cheap on eBay. But really unique or expensive lenses will get me to spoil a whole day if necessary. What is a couple hours of your time worth? For instance, you may have to put a lens in the freezer and then use a heat gun to expand a part to get the thing disassembled. I usually budget an hour but it can turn into an all day project once in a great while. But some people just like the challenge, so the time does not matter if it's just to try to accomplish the job.

    I have a few comments about using white vinegar (dilute acetic acid) per my recent experience. I have noticed that one rear element (rearmost of four) in a Minolta Hi-Matic E (Rokkor-QF 40mm F1.7) I was trying to harvest and re-mount in M42 is probably made of plastic or other material (other than glass), it lost material in vinegar (less than 10 minutes) that looked like white powder. At the same time I was soaking the Front-most element (glass) of that same lens, and the coating formed some type of salt with vinegar added and became a bit opaque, which I now have to polish using micromesh paper and lapidary diamond paste. Just be aware and warned that this happens. Using Alcohol (about 90% concetration), Acetone and 3% Hydrogen Peroxide does not have this same problem, for now I have stayed away from using common Ammonia (cleaning type). Some people use 50/50 mixture of ammonia with peroxide.

    Not sure if this would damage the coatings, but using a table spoon of food grade citric acid to soak it in is probably better then vinegar. That stuff cleans anything. People can use it to clean contact lenses, so I don't see why it would be a problem for camera glass. And before replacing the lens, I'd make sure to clean the inside of the body and right before putting in the lens, I would hold it upside down and use an electric air blower to blow out as much dust as possible, same with the lens itself, and then replace the lens while the body is still upside down. I would never dry it with any kind of paper. Fibers will always come loose and can take a while to get off even with a several passes of a microfiber clothe.

    Couple issues before you open your lens and do this procedure. 1. If your lens has perfect infinity focus, you will ruin focus at infinity unless you return the front element to the exact position (good luck with that). 2. If the element you are cleaning is a canadian balsam cemented lens you risk balsam separation if your water is hot enough. 3. It is more difficult to clean these elements than what is shown. Depending on the naitive lens coating, you will probably end up with some sort of dust on the lens. This fungus around the rim probably did nothing to the image quality but provided a good example. To kill (not remove) the fungus, leave it in the sun for a day (make sure it doesn't rain) or bake in oven for 20 minutes at 150 - 200°(F) (no more! see #2 above).

    I use hydrogen peroxide followed by Ronson lighter fluid. I use brand new microfiber cloths for the first washing with hydrogen peroxide and then I use two q-tips with the Ronson lighter fluid and then use the dry ends to get the lens fully clean. Then I inspect it carefully with light at different angles and repeat if needed. I have not tried soap and vinegar. Those might be interesting middle steps if the lens is badly covered. Sometimes the fungus has etched the coatings so you can't get it perfect (I have seen people polish with diamond dust, but I an not sure that this does not do more harm than good). Besides the lens vise, I also have the set of rubber lens cups, precision tweezers and precision screwdrivers. You may also need acetone if someone has cemented the edge of the lens or the lens rings with shellac. Before I start, I always kill the fungus with UV. If the lens is small enough you can use a cell phone UV sterilizer. If it is big, you have to modify the sterilizer or make your own. The Angry Photographer has good videos on lens cleaning, and I have seen others that are also good.

      If you slip while using an adjustable metal spanner wrench (I have 2 different sets of them), the resulting scratch across the surface of the lens will make you much more careful the next time. Until you have done this a few times, try using the hollow soft-rubber tapered cylinders, which grab the edges of the rings that hold the lenses in place. Amazon, among others, has a selection to choose from. With these rings, the pressure on the retaining rings is even all the way around, and it is much more difficult to inadvertently ruin a lens, while unscrewing the retaining rings.

    I'm not certain if you want to rub camea lenses, with anything including your hands. This is especially true of internal lenses that are protected. It's better not to touch a camera lens and to soak it instead for at least a few mins. One solution I found that works is equal parts of hydrogen peroxide and ammonia. If fungus isn't removed the first attempt soak again for up to 20 mins. Once the fungus is gone then you want to rinse the lens with water without touching or rubbing the lens sides.
    Once the solution has been rinsed off, use a lens spoofer to blow away all the water droplets. With the water gone, use a clean microfiber cloth to lightly wipe the lens.
    Then inspect the lens under a bright light. Check from both sides and with different angles of light to be sure that all the fungus is gone and you have no dust or smudges on the glass. If it looks good, set it aside on a clean soft microfiber cloth and cover it up to prevent any dust from settling onto it. Repeat the cleaning process on any remaining elements.
