I have a pen where the cap is a rubbery stylus intended for a capacitive touchscreen use, such as that for iPad.
I've had it for about 14 months now and the rubbery tip has almost lost all effectiveness. It's like a $20 or $30 pen with a nice smooth pewter finish and the tip in the cap. It's my favorite stylus, a decent pen for signing things, and other than said tip, it still has good life expectancy yet. My iPad has had a Zagg shield on it ever since it was new, and continues to respond just fine with other styli and my fingers, so I'm pretty sure it's just this one unit.
Is there something I can do to bring this stylus back to life?
