I have used this for well over 6 months with excellent results.

THIS IS NOT TO BE CONFUSED WITH ORDINARY WINDEX WINDOW CLEANER!

Ciao.

Hi, Here is what Apple Support advises on cleaning laptops. As for getting rid of the stripes, try cleaning again as shown below. If they persist, you should take it to an Apple store Genius Bar, if possible.

MacBook, MacBook Pro, and MacBook Air

When cleaning the outside of your MacBook, MacBook Pro, or MacBook Air, first shut down your computer and unplug the power adapter. Then use a damp, soft, lint-free cloth to clean the computer's exterior. Avoid getting moisture in any openings. Do not spray liquid directly on the computer. Don't use aerosol sprays, solvents, abrasives, or cleaners containing hydrogen peroxide that might damage the finish.

To clean the screen on your MacBook, MacBook Pro, or MacBook Air, first shut down the computer and unplug the power adapter. Dampen the included cleaning cloth with just water and wipe the screen. Do not spray liquid directly onto the screen.

Important: The bottom case of the MacBook (13-inch, Late 2009) and MacBook (13-inch, Mid 2010) uses a soft nonslip material. Use a 3M Gray Microfiber or soft dye-free, lint-free cloth to clean the bottom case.
