As the dust gets accumulated, the four pads on the underneath surface of the mouse get sticky, increasing friction, therefore, causing difficulty in moving the mouse. To get things back in the right way, you must give a glance over all the necessary information we've combined for you.

At first, of course, the most important step is to disconnect the laser mouse from the computer's USB port. Turn your computer off to prevent any electric shock you can get. The laser of this mouse is extremely dangerous for your eyes so unplugging the mouse is very crucial. If the laser mouse is wireless, either take out batteries or simply turn it off.

Then take a white piece of paper and place it on your desk. Keep the laser mouse in your hand and move it a few times from top to bottom on that paper bearing in mind that you have to apply moderate pressure while doing so.

Once you're with this, you'll be surprised to see a layer of grease and dirt on the paper. Hopefully, most of it would have been removed, if not nothing to be worried about. Just take a slightly wet piece of cloth and clean with it. Repeat the process a few times and use nails to remove leftover grease. Dirt accumulated around the pads can be removed using a toothpick. The rubbing alcohol can help you get rid of hardened grease that is almost impossible to remove. Utilize a Q-tip to remove unwanted particles around the laser sensor but don't apply pressure on it.

Dry the mouse with a soft cloth and for a few days, you are advised to let it fully dry before being used. Once it's dried, reconnect to the USB port if it's a wired one. If it's wireless put in batteries or turn it on and continue using your laser mouse.
