Can we clean laptop screen with Colin? Or something else?

Yes you can clean your laptops screen using Colin but not the blue one. Colin does have a white colored variant (Colin Gadget cleaner) which can be used to clean the laptop, mobile, TV screens. If you are using the blue Colin liquid, then do not spray directly on it. I have seen blue Colin sprayed first on the cloth and then the cloth is used to clean the screen. This does not damage the laptop, mobile screen from the exposure of chemicals from the Colin.
