Let’s get out the cleaning supplies. Here’s what you need:
Dip the toothbrush into the soapy water, shake off excess water (cause you don’t want to soak the mouse), then scrub the outside of the mouse thoroughly to get rid of all the grime. The bristles of the toothbrush will help you get the mouse cleaner than with a regular cloth, because most mice have a textured surface. Repeat this process at least once with soapy water, then twice with clear water until it is clean.
Clean the mouse ball with soapy water as well. After removing all the dirt and particles, be sure to rinse it well with clear water to avoid sticky soap residue after it dries.
Now it’s time to attack the grungy guts of the beast. First use a toothpick to loosen the dirt that’s caked around all the rollers, then use the tweezers to carefully remove the dirt without dropping it into the mouse. This might take a little while but with some patience you’ll get all the chunky stuff out of there.
Once the worst is removed, dip a Q-tip into the rubbing alcohol (don’t soak it too much) and proceed to get the last of the dirt off of the rollers and make them nice and clean.
