Tearing Off the Rubber Layering of iBook Clamshell

Thanks to a mixture of plastic and rubber casing, the iBook Clamshell is extra-ordinary tough against shocks. The rubber layering, however, is very easy to have marks appeared on it.

What is the nature of those marks?

Today I tried to tear off this rubber layering from the iBook to check the nature of those marks: are they remain inside the rubber? Or between the rubber layer and the plastic shell? 

I have a damaged graphite case for this experiments.

I started from a cut made by the cutter. And then I tore the plastic off with force.

The plastic attached firmly with the plastic shell. Huge amount of force was used. It is therefore unlikely that those mark are dirts penetrated between the rubber layering and the plastic shell.

There are 4 knots close to the battery door. It could not be tore off without the aid of a cutter.

Finally, I took apart the rubber layer from the plastic case. The plastic shell is still remaining clean. I conclude that those are not dirt, instead, discolour which could not be eliminated by water, detergent or alcohol.

So, if your iBook Clam has marks appear.  Do not try to clean it because it could not help. It is better to have a replacement instead.
