May be, I am too careless that I didnít put any cover or something on my iMac 27". After a few months of use, I found that it is having dust on that and I tried to clean that with a cloth. Dust from the top of the screen can be cleaned easily but I can see that there are also dust inside the screen that I canít clean. It is too much at the edges of the display. Now it is making my working experience on iMac too bad and I want to clean that somehow. I donít know if the upper screen of the iMac can be removed to clean the dust from it, so I am posting here to have some suggestion from you people. Can somebody tell me any possible way to clean that? Thank you.
