This may seem odd, but I think my iMac is melting. I started to clean my iMac with a simple cleaning cloth then i realized spots on the screen. The aren't really visible when the screen is on, but you can still kind of see them. Not only that, the quality of the images on my screen seems to be deteriorating. It is only visible under light. I have attached some photos, but i wanted to know if anyones iMac has done this before(regardless of size, but post it in case), and if apple will fix it?
