HOW TO REMOVE FUNGUS FROM THE CAMERA LENS WITHOUT OPENING IT?

I am pretty sure most of you have never heard about lens fungus. But it’s a real thing, and you have to deal with it in humid conditions. Let’s straight dive into the part of removing fungus in-camera lens without opening it.

  • UV treatment:

The best way to treat stubborn fungus without dismantling the lens is to give it a little UV light. All you need to do is keep the camera under sunlight for about 2 to 3 days.

UV light kills fungus so, this much exposure should be enough to eradicate any lens mold. Make sure to remove any UV filter if you have it attached in front of the lens.

Unfortunately, barely killing fungus doesn’t mean completely removing it. Unless it’s not hampering the quality of the pictures, it works. But, if it is doing bad to your picture quality, then continue exposing the lens in UV light every day.

UV TREATMENT
  • UV lamps:

If you are not a fan of stepping out in the sun, there’s another way you can procure UV light in a fungus lens. You have to keep the lens under a UV lamp. UV lamps are highly affordable and are available easily in the market. All you have to do is;

  • Take a stainless steel container and fix the lamp in that box.
  • Once the box is set, place the camera in such a position that the lens faces the lamp.
  • Use silica get to absorb the moisture faster. Pour a kilo of silica gel into the box and let it sit there until it changes its color from white to blue.
  • As soon as you start seeing the color change in silica gel, you can infer that the process is done.
  • Hydrogen Peroxide:

Cleaning fungus inside the lens is one thing, while killing fungus is an entirely different thing. Killing fungus is a tricky job. Even if you somehow manage to clean the core of the fungus, temporarily, you will feel that the job is done, but in reality, the fungus leaves its spores behind that can attack the lens and again infect the lens.

If you follow this procedure, there’s a high possibility that the spores will be gone too. Many professional users suggest hydrogen peroxide is the best method to wipe off fungus from the very core of the lens. A mixture of Hydrogen peroxide and ammonia works best. Things you need to do;

  • Prepare a mixture with 2% Hydrogen peroxide; 4% Ammonia; 94% distilled water.
  • The mixture should be kept prepared half an hour before cleaning.
  • You have to soak the mixture on the lens for some time.
  • Wipe the mixture with a soft cloth.

All the described methods are great for removing fungus from the lens without opening it. But, also note this point that this method only shows results when the fungus accumulation is fresh. If you delay in cleaning, there’s a possibility the fungus has already entered the inner core of the lens, and there’s no other way than to dismantle and clean it from the core. 

CONCLUSION

Lens are safe from fungus as long as you keep them in a waterless and pleasant condition. The camera lens fungus problem is easy to treat, not very serious. It can get serious if you neglect cleaning them frequently. With proper lens fungus cleaning and maintenance, you can increase the lifespan of camera lenses so they can last for a decade and help you get world-class picture quality.
