A laser mouse is a dramatic improvement over the ball mouse, which gets clogged with dust. It's much easier to clean a laser mouse than a ball mouse. On the underside of a laser mouse are four soft pads which allow it to slide. The pads get sticky when dirty, making the mouse hard to move.
Turn off your computer to prevent shock while you clean a laser mouse. Place a clean, white piece of paper on your desk. Computer paper works fine.
Hold a laser mouse on the bottom edge of the paper pressing gently. Slide it from bottom to top of paper while applying gentle pressure. You should see a dark streak on the paper from dirt and grease left behind.
Look at your mouse pads to see if all grease has been removed. If not, use a fingernail to scrape off any remaining grease.
Get a dampened soft cloth or paper towel if the grease is too stubborn to remove with a fingernail. Make sure the cloth or towel is barely damp, not dripping. Moisten the mouse pads. Repeat Steps 2 through 4 until mouse pads are clean.
Clean the top and under surface of a laser mouse with a soft, damp cloth. Use rubbing alcohol or mild soap for stubborn grease. If you need to remove dust from the hole containing the laser, use a Q-tip.
Dry a laser mouse thoroughly with a soft dry cloth before using. If you accidentally got liquid inside of it, don't use it until it has air dried, which may take several days.
Things You'll Need
Piece of clean, white paper

Clean a laser mouse pad or table with mild soap and water, and dry with a cloth.
Don't use anything sharp to clean a laser mouse, such as a razor or knife blade, because it could scratch or damage the pads.
