Static Cling - why is its effect permanent ?

[ramonegumpert]

Hi,

I did some search on Static Cling products like decals .
They work using a static charge concept.
But static charge can easily be grounded and cause the charges to be neutralized.
So, why is it that static cling products do not lose their static effects?
Any ideas?

Thanks for reading.

I think it has something to do with the decal being a particularly poor conductor. So poor that you can't effectively ground it.
The electrons are not free to move around through the material, but they are free to crowd near the surface - enough to provide an attraction.

This is naught but an educated guess.

Thank you sir.

Glad to see that my question has merit. Its not a simple question after all :)
Hope to hear more responses.
Physics is fun!
