Cleaning the screen with protection, back.

So I have a screen protection on the screen of my CF-30.
It's scratched and very dirty.
I want to remove it, clean the screen and eventually put a new screen protection on it, but :

I'm a little afraid, my CF-30 works nearly perfectly, and the touchscreen, the anti-reflective, all this stuff seems in a good state.
I don't want to put the mess on this, and I don't know from how much time this screen protection was on it.
What will that mean, to be carefull? Don't touch it?

 

Lol..The touchscreen was designed to be touch and don't worry about it. It may beocome dirty or something like fingerprint mark but is usual to this type of unit with builtin touchdcreen. Then you can clean it by regular LCD cleaner or a bit of soap solution with water and then wipe it out with micro fiber cloth.

ohlip

 

Ok, thanks.
But the question is about the screen protection, abd how to remove it carefully, to avoid :

I don't want to remove the coating, so how to do this?
With an hair dryer, it's a good idea?
