How to clean the Mighty Mouse's scroll ball
Authored by: bridgesmj on Apr 22, '07 12:12:13PM
Hi I just wanted to say that I have also had success with cleaning my Mighty Mouse's scrollball.

I bought one off of ebay (the guy sent it from the US to England, thanks very much) I guess he sold it 'cos the mouse didn't work properly, although he didn't say this in the listing! Anyway, needless to say the scrollball wasn't working, and now after about 4 months I decided to fix it.

I tried the blow down the hole and wipe with strong alcohol methods, but these were to no avail. I then tried the dig out the dirt with a knife approach, but the result was the same.

After this, I decided that destruction was the only way ahead. I managed to take off the inner rim with no problem, and the outer rim also came off without snapping (I was able to stick it back on using Airfix glue at the re-assemly stage).

The whole reason that I'm writing this to you all however, was that once I had got down to the bare bones of the scroll wheel, I was truly disgusted at the amount of grime I discovered. This photo shows exactly what I mean. It's no wonder it wasn't working. The little black magnets are pretty cool, but you should take care not to drop them, as if you do I'm pretty sure that they'll find their way into the nearest crack.

Anyway - I just wanted to encourage those people who were considering the destruction method to go ahead - I found it to be wholly successful, and I'm hoping that it will continue to work for longer than it would if I'd just brushed it out (if that had have worked...).

How to clean the Mighty Mouse's scroll ball

YES. It worked! I could scroll up but not down.. of course. Apple's instructions didn't work too well, so out came the Q-Tips, alchohol, toothbrush, and a stack of clean paper. Thanks for all the hints, they worked.

I liked the idea of rolling the mouse upside down on the paper, because it was as lint free as I could get. I wet the ball with the alchohol (using the q-tip), rolled it around with my finger to spread the moisture (while pressing down on it to make good contact with the inside parts) and then rolled it upside down vigoursly on the paper. Then I carefully scrolled the ball and picked up the loosened dirt with a clean wet (alchohol) q-tip.

With this came progress, but it wasn't perfect, so I crammed the tip of my toothbrush down in there and scrubbed at the connectors and then repeated the whole upside down rolling thing and got out more grime. My old friend is back!!

Now I'll take better care to do regular maintenence with alcohol and q-tips...
