Why isn't my MacBook screen as bright as it should be?

What would happen if you spray the iKlear solution directly onto the macbook screen? PLEASE HELP?

• A lot of people have been telling me recently that I shouldn't do it but of course they waited until after I did it to tell me. I have the iKlear and a macbook 13." I sprayed the solution onto the screen but people told me after to spray it onto paper towels/rags and then apply to the screen. Now I'm really worried that I just accidently broke my screen. How long would it take for the screen to begin to show the signs that it's broken? I didn't let any fall between the cracks and I made sure to wipe it off thoroughly.... I'm definitely never going to spray directly onto the screen anymore. I reset my system afterwards and the screen looks fine. No damage. So can it still show up? Do you think my screen will break?
