Thread: Filter has fungus

  1. #1

    Default Filter has fungus

    Hi,

    If i realise that my UV filter has fungus, how should i wash properly, before using it again?

    What i did was to run under tap water, rub off the glass clean and air dry the filter.

    Is this good enough? Will the fungus grow back again?

    Any special liquid solution that i shld use to get rid of fungus?

    Use lens cleaning solution. IPA may help too. Just water will not kill the fungus.

    At least some Dettol would be appropriate, right? Secondly: do clarify why your filter grows fungus. Hope your camera was not stored under similar conditions..

    Oh, my camera and all lenses are safe in dry cab.

    I kept this filter in another place, far away from my cam and lenses. the reason is coz this filter is those lousy FOC given by the shop. So i didnt care too much about it anyway. last night i rem abt it, took it out and realised it has fungus spot.

    I got no Dettol at all. Hmm... should i put in under the sunlight for one day? will it help?

    If it is a cheap filter the better throw. I don't use any UV filter at all, lens hoods are my choice. But for those people who need a UV filter to feel safer I suggest: get a good one and take it off at night.

    try hydrogen peroxide
    or
    clear ammonia+hydrogen peroxide 4% 50-50 mixture.

    It's said to be able to clean off fungus.

    some user claim that they use mama lemon.(or any soap u have) you can try... just water is not good enough. If condition is really bad and that filter is really cheap anyway. maybe you can just discard it since cheap filter will have lots of problem with flare ..etc etc.

    Think soap and water is ok, after which dry it and put in dry cab. but since its cheap or foc type. maybe no need to bother much.

    Since it is FOC. Throw it away and get a new one. No point trying to remove the fungus... it might infect your cameras and lens if not done properly.
    I am not a photographer, just someone who happened to have a couple of cameras.

    Oh yeah. It's some made in MY filter that comes with kit lens. I'm not a filter person. Never use this filter at all. I always take pics without filter.

    But now I got another lens, replacing kit lens. So I itchy to use a filter on this lens. So I took out this FOC MY filter, thinking I can use back.

    Guess I have to get a new filter then

    relax la... it's just fungus.. wash with soap or some dishwashing liquid, and let it dry before using.
    Fungus isn't some kind of disease, like SARS. Doesn't need much effort to get rid of it
