Will spraying compressed air into keyboard clean it?

Will spraying compressed air into a laptop keyboard really clean the stickyness or what ever junk is inside? Or just putting rubbing alcohol around the key and spraying it with compressed air so it cleans it off. Does that really work? Because I spilled gatorade on my laptop like 1-2 weeks ago, everything is fine, its just that my keyboard is kind of jacked up at the moment. I have no idea if my keys are pop off or I need a profesional to take it out. My laptop is a samsung notebook QX410-S02. If they aren't pop off. What kind of repair shop should I go to? Would Best Buy work?
