HP-30B screen protector secrets?

[John Garza (3665)]

Any secrets on how to remove this cleanly?
All products with screen/plastic protectors these days are easy to remove and leave no residue. Except HP and its Asian surrogates. A huge quality failure in my opinion. My machine is basically unusable. I've tried water, windex, goo gone, ipa. No good. Kimwipes get torn and leave paper bits stuck all over the screen. I'm afraid to scrub too hard for fear of scratching/dulling the screen.

Anyone else have a problem like this? Is the machine a lost cause?
