    Just wondering.............

    For some reason projector lenses seem to act like a magnet, not sure if it's a static thing, or a heat thing, but dust that's floating by seems attracted to the front of a projector lens.

    After only a short time, looking at the lens when running (from side on) you see bits of fluff ect on the lens surface.

    Now I know this won't have any major effect unless it got really bad, but was wondering, do any of you guys evey clean the front of your projection lens ?

    If so, what do you use ?

    I know my father years ago used to have a very VERY soft brush with a rubber puffer behind it, which he used to clean the lens on his super 8 projector with...

    Good idea, bad idea, anyone ?

    I would use compressed gas before any cloth,,, just seems safer to me.
    Make sure you dont spray any liquid though, that may damage the lens...
    I know you can get compressed gas from computer stores and diy places but maybe elsewhere..

    hehe, well as ritz said, if you want to clean it properly then some course sandpaper will do the trick perfectly.
    P.S. I find superglue is a brilliant solvent to get the hard to reach stuff off, if you are still struggling that is...

    Yes, I have sprayed with a can of air but it does not shift the dust that's stuck on the lens surface.

    The projector is in a non dusty room and only has 40 hours on the clock, so god knows what other peoples are like.

    I don't suppose many people bother about it.
    I was just wondering...

    Not sure about the brillo pad idea.
    I was thinking of a jet wash with some sand added to the mix :)

    dust also burns quite well so if you held an oxy-acetelene torch to your projector im sure that would clear it up...
    If it really doesnt shift I wouldnt worry about it, if it disrupts the picture then you can use a lens cloth for glasses (that would be smooth enough) but still wouldnt really do it unless I had to...

    I assume that you must be able to get some sort of wipes from a camera shop. I keep meaning to call into one and see what they have.

    My lens is fairly dusty as I don't bother replacing the lens cap because for one the projector is fastened to the ceiling and two unless you are very steady it's very easy to adjust the focus by mistake.

    I must admit. I take great care of my little baby.
    Not only do I replace the lens cap every time, I also slip a dust bag over it after cooling down, so dust does not settle on it whilst it's not in use.

    Aaawwwww....... **big cute eyes**...... :blush:

    Seriously, soft lens cleaning cloth is the thing - get something appropriate from your nearest photography (had a few glasses of wine, spelt that veeerrry carefully....) shop. As for the "blanky" when it's being put to bed........ I wouldn't go that far!!

    Well.. I put mine back in it's original box and plastic bag EVERY time, !!! :rotfl: :rotfl:

    After only 34 HRS i have had two green circular, and one faint blue circular spot on the screen, so i have cleaned my LCD panels twice now and on both occasions they have dissapeared (luckely).

    I don't see my living room as being very dusty though ?? :confused:

    Is this normal ? I mean i dont want to clean those LCD panels after 2 or 3 movies everytime !!! :mad:

    Cheers

    I've never cleaned the LCD panels in my AE100 - after 2 years I still don't see any dust blobs...... I've certainly not noticed anything like them in normal viewing. It's in a dedicted room which gets no traffic, and the filter is cleaned regularly... maybe that has something to do with it.
