Note: Newer version of the procedure is here
I use it all the time. I’m taking it everywhere with me together with my laptop. Thanks to it’s wirelessness it’s easy and nice to handle. I like this mouse a lot. The only problem I have encounter is dirty roll. It slowly stops working – first in down direction. if you press it a little bit dipper it still works, but only for a moment. Then other directions stop working too. Apple’s provided method of cleaning usually works only for couple of minutes.
So out of desperation I started to look for methods to disassemble it. Unfortunately Apple decided to glue it together so you can’t disassemble it without breaking things. Although some say you can glue it back I don’t like this solution at all.
Some googling later I think I have found the solution. If Apple’s cleaning method doesn’t work for you anymore proceed to second step. Find a flat surface and lay a sheet of white printer paper on it. Then turn your mouse upside down and, for about 1-2 minutes, do this:
After some time you should start seeing small dirt leaving your mouse and staying on the paper. Don’t expect too much – there isn’t much space inside the mouse for dirt to accumulate, yet it’s enough to prevent it from working. Anyway judging from amount of dirt my mouse left on paper it should work like new – and in fact it does!
