This may sound strange but try "Ponds" hand cream,I have try a number of hand creams and most of them work well.But with any fungus if it is light you can clean it, if is etched into the surface of the lens, then that is the end of that.
You may need a Lens Spanner, and a rubber pad to get into most lenses. |

I have had very good luck with dish soap and warm water. Just make sure that if you are working on a lens group that no soap/water will get in between the elements.
I ususlly put a couple of tiny pieces of duct tape over the tips of my spanner to reduce the possibility of scratching something if I should slip when trying to remove a tight ring.
Very light fungus can usually be cleaned. Fungus tends to etch lenses pretty quickly, so I would just toss the lens if it looks like the fungus is pretty extensive.

If soap shifts it, then it wasn't fungus! Use ordinary vinegar. It is cheap, quick, easy, and always works.
Whatever you apply it with, use an absolute minimum of pressure. It is very easy to scratch a lens. |

If the fungus is NOT etched into the glass - then it can be removed with Eucalyptus Oil or Citrus Oil. You my have to apply a little pressure using a cotton-bud. Clean up afterwards with petroleum spirit and the finally clean normally with Windex or a proprietary lens-cleaner fluid. |

I haven't tried it, but denatured alcohol should do the job. It will kill the fungus, and leave no residue of its own. I've seen straight methyl alcohol recommended, too. |

Some times oil haze can look like fungus, I have purchased lenses for a low price because of this only having to clean the glass. There has to be a judgement call, Is the lense pricey and worth a try or not. Old Leica Summarons get a haze that degrades the price and it only needs cleaning. One thing to be very careful of, the inner coatings of some lenses are softer and can be damaged easily. Good luck...Don |

I have used Fiftyfifty's tip to use hand cream to clean light fungus from lens elements and it does work. I have only ever used it on uncoated optics. Incidently I have seen this suggestion in the repair manual of one of the major lens manufacturer's. (sorry guys cannot recall which one) Even more off the wall cigarette ash can be used as a mild polish on optics.
Have to go now to my Ebay site I am marketing a high tec lens polish at £10 a gram ! |

Imbecillically cute, really. I guess any fungi will dash off for fear of being video-digitized, won't they? |

Why did they bother to 'publish' this! It does not even show the correct way of using lens tissues.
For the uninitiated:- The correct way to use lens tissue is to first roll a sheet into a tight cylinder. Now tear the roll into two pieces. The tearing action produces two areas of soft, brush like fibres, which are used to apply any cleaner and wipe the lens surface clean. In the 1950s, bulk supplies of 'Whatman' lens tissues contained instructions outlining the above method of use.
Using tissue as shown in the above video, will produce fine scratches on any lens coating. In fact the modern 'microfibre' lens cloth is a far better product for any optical cleaning. |
