How do I get rid of black mold growing on the bottom of my computer mouse?

I got an old mouse pad from my father some years ago and when I got a new mouse pad I noticed my mouse leaving black spots all over it. I used to clean the mouse with bleach but to no avail. Since then I've ditched both mouse pads and just have a desk protector. The mold still comes off the bottom of the mouse specifically from the glider pads. I've let it sit in bleach several times over the past few years to no avail. I use straight bleach, usually for five minutes and clean it with Q-tips and paper towels to try and remove all the mold in the crevices. It always comes back and I can't think of anything else to do except throw the mouse away. The problem is it's a nice G9 laser mouse and I can't really afford to replace it with a newer similar mouse at this time. I was thinking about just taking the pads off and soaking them in bleach overnight but then gluing them back on might be impossible, ruining it forever. I've almost given up hope but figured someone might know. I read about mold problems people have in basements etc. and it seems like whenever mold is involved things get ruined/abandoned/burned or thrown out. Do I need to soak it every day until the problem goes away? I'm probably going to have to throw the clear plastic desk protector out as well, if bleaching doesn't help with that either.
