How to Clean a Laptop Touchpad

Turn off the power to the laptop. You can also unplug it and remove the battery to avoid any potential short of the system or shock to you.
Dampen a cloth lightly with the distilled water. Dab off any excess onto the second cloth or dry part of the same cloth. Rub the touchpad with light pressure to remove the dirt. Dry with the second cloth.
Mix one part distilled water to one part isopropyl alcohol in a bowl or cup for a stronger cleaning solution if necessary. Moisten the cloth with the solution and rub the touchpad with light pressure. Wipe dry with the second cloth.
