Do not use sprays, solvents, or abrasives do not attempt to use any solvents on the LCD display either directly (especially!) or indirectly. Do not spray any type of liquid directly on the computer. Avoid getting moisture in any openings and be very careful not to get the damp cloth around the trackpad edges or around the inside edge between the monitor and its bezel.

Use a very lightly damp, soft (if you can squeeze the cloth very tightly and even a drop comes out, its still too damp), lint-free cloth to clean the computer’s exterior. What kind of alien dirt do you have that doesnt remove with a soft damp cloth? 😕
