Laptop cleaning, hard stains help?

I am trying to clean my laptop with these hard stains that I don't know what they are there like kind of white and stuck to the computer. 

I tried using alcohol and try using scrubber sponges and but it doesn't seem to be off, it takes some hard scrubbing  and time to make it go away. I wish to know if there was a way for me to remove these things without damaging the computer. The details of the stains is that they're very hard to remove with a sponge scrubber using alcohol only lightens up the color of the spots it shows me where they are but it takes a while for the scrubber to diminish the amount of the stains there but it still isn't enough. 

Any ideas equipment , material, anything that I could use to clean the laptop, removing the stain without damaging the laptop?

    Use isopropyl alcohol. It does not damage electronics if used correctly.
