My magic trackpad seems to have gotten dirty in the button.
I've tried swabbing around the button with alcohol but I still, at times, have to lift the trackpad to release the mouse click.
Do you have any clever ways of cleaning it?
What you need to do:
This worked for me, so I hope it will work for you!
I used an old, clean toothbrush and it worked perfect. I used a tiny bit of water, but I am sure it would work without that (in reflection i would try it first WITHOUT WATER as to not risk damage of the computer parts). I just flipped over the trackpad, pushed the button in and worked the toothbrush bristles into the seam all around it. I instantly could feel the button not sticking.
