What is the best way to oil a mouse scroll wheel?

I have a mouse with a bit of a scroll wheel issue, as it will squeak every now and then, and is a little sluggish. What would be the best way to oil it? Would WD-40 work?

Thanks in advance!

Had a Razer Deathadder squeaky mouse wheel. I used a little molybdenum graphite powder. Worked like a charm.

WD-40 would not be a good idea. It is probably lint and fibers collecting on the wheel's axel. Most mice are easy to disassemble, there may be covers over the screws on the bottom of the mouse. Once the axel is clean then it should be able to move in its sockets without any need for oil.

You think that could cause the squeaking as well?

I would say so.

I know this is pretty old but I'm dealing with this problem now and I've already cleaned the whole mouse. I disassembled it, took the motherboard out of it, and isolated the mousewheel to clean it better. I cleaned it using 99% pure alcohol and let it dry for hours. Now my mouse has 0 particles of dirt/whatever and 0 cat hairs in it.

However, the mouse wheel seems to be as hard as before, if not harder. Before cleaning it with alcohol, I noticed the wheel itself had a layer of some oily substance, so I think I DO need to re-lube it. What can I lube it with?

Usually and very small "dab" of 3 in 1 oil with a Q-tip will do.

When you say oil, what do you mean by that? (I know this question is old, but the issue persists)
