CAUTION:
Avoid strong cleaning solvents that can permanently damage your computer. If you are
not sure that a cleaning product is safe for your computer, check the product contents to make sure
that ingredients such as alcohol, acetone, ammonium chloride, methylene chloride, and hydrocarbons
are not included in the product.
Fibrous materials, such as paper towels, can scratch the computer. Over time, dirt particles and
cleaning agents can get trapped in the scratches.
