Hi Sam,

Rub your finger over the rubber.  If it doesn't grip your finger it is definitely dead.

You can also take a look at the rubber.  Hold it on an angle and if you can start to see the pimple showing thorugh the rubber, it is getting worn.

Make sure you do these two things after you have cleaned your bat.
