I GOT WINDEX IN MY LAPTOP SCREEN.. hml>:(?

okay so yup. I know what you're thinking, what kind of idiot would do this? well it was an accident because my sister got it greasy. I ALWAYS spray just a tiiiny bit of windex on a paper towel and cautiously wipe my screen. But i was so busy arguing i forgot. So now my 1/4 of my screen is full of some blobby white soapy thing. I bought this laptop from best buy and it still has it's warranty. Do they cover it?
