Do not spray any liquids on the LCD screen directly, and do not use paper towels, this can cause
scratches on the LCD screen.

Always apply the liquid to the cloth first and not directly on the parts you are cleaning to avoid
dripping the solution directly into your computer or laptop
•
Wipe the cloth across the display in one direction, moving from the top of the display to the
bottom.

A solution of water and isopropyl alcohol. This solution can be used along with the soft cotton
