Hi There again,

I live in a rather dusty house because we always have the doors and windows open which means that dust from inside often gets into my house and it seems to be attracted to the screen on my iMac so I was wondering how to clean it.

I have used the little cloth that came in the box with my computer but I was also wondering if it would be ok to wipe over the screen with a damp cloth and then dry it off or if this would damage the screen (I don't want to do it if it is going to spoil my screen) so I would really appreciate so input as to whether or not this will be ok

Huge Thanks

Jason

    Jason,

    Welcome to Apple Discussions.

    Your owners manual says:




    *Cleaning Your iMac*

    Follow these guidelines when cleaning the outside of your iMac and its components:

    1. Shut down your iMac and disconnect all cables.
    2. Use a damp, soft, lint-free cloth to clean the exterior of your iMac. Avoid getting
    moisture in any openings. Do not spray liquid directly on your iMac.
    3, Don’t use aerosol sprays, solvents, or abrasives.



    *Cleaning Your iMac Display*

    1. Use the cloth that came with your iMac to clean the display.
    To clean your iMac display, do the following:

    1. Shut down your iMac and disconnect all cables.
    2, Dampen the cloth that came with your iMac—or another clean, soft, lint-free cloth—
    with water only, and then wipe the screen. Do not spray liquid directly on the screen.

    Follow the instructions and it will clean up fine.

    I must admit I do not disconnect cables. I just shut off the iMac, dampen a soft cloth with Windex, wipe over the screen, then polish with another soft cloth. Works for me....

    Windex contains ammonia which is not safe for use with any LCD screen. Ammonia-based cleaners may damage to your screen, and said damage will not be covered by Apple.

    The new iMac's have a glass screen that Windex does not harm.

    Read the manual! It does not say Windex is OK. It clearly says:

    Dampen the cloth that came with your iMac—or another clean, soft, lint-free cloth—
    _with water only_, and then wipe the screen. _Do not spray liquid directly on the screen_.

    You may be harming your screen and not be aware of it.

    Read the part where it says "Do not use window sprays or cleaning products containing ammonia, chlorine, or abrasive ingredients."

    Your decision if you want to go against Apple's strictures, but don't be surprised if you do damage the screen, nor complain when Apple won't repair it under warranty.

    The key word in the instructions is "spray". Of course spraying directly on the screen and taking the chance of dampening other areas of the case is not a good idea, so they recommend a much safer method to the general public. That is probably the reason they do not recommend owners to open the case of new model iMac's as they did with the early models.

    But to close the argument; the method I described works well for me, cleans great, and in my estimation poses no threat to rest of the computer when done as described. However, if one carelessly sprays Windex all over the case...well that's a different story. But applied with a small damp cloth with a small amount of Windex on it poses no threat to the glass screen. Ammonia doesn't hurt glass and does a much better job for me than plain water that streaks.

    I'll live with my ignorance with a clean screen....

    The key word in the instructions is "spray".

    The instructions say "sprays OR cleaning products", not "cleaning products that are sprays".

    Ammonia doesn't hurt glass

    No, but you're presuming that the LCD screens Apple uses have no coating on them that could be damaged. Many do.

    But suit yourself; it's your risk. But I would suggest you either avoid recommending that to others or caveat your advice with a statement that Apple says not to use cleaners with ammonia.
