how to clean BlackBerry Tour trackball without removing trackball. if your Blackberry Tour 9630’s trackball is not responding properly, you can try and clean the trackball. The most effective way I have found without removing the trackball is to get an alcohol wipe and lightly roll the trackball with the towelette . you should make sure the BlackBerry Tour device is switched off or keyboard locked so you don’t inadvertently change or send things.

or you can clean BlackBerry Tour trackball by running a brush with denatured alcohol over the trackball and trying to clean the rollers. By cleaning the rollers, it will respond better to the movement of the trackball.
