Acetone to remove LOCA?

Does anyone have any tips on removing loca from the iphine 5 lcd?

The samsung range litterally rolls off and then I can clean with Alcohol and finally window cleaner.

But the stuff on the iphine is much more robust. I've bought some potent stuff from HongKong but it just smells like acetone. But im sure this stuff would be more harsh than this stuff? Or would it be a mixture of acetone & alcohol?

Or is there anything else out there (readily available in the UK)

Also. Do you guys unsolder the backlight away, as I've torn a couple by the LEDs when trying to remove it (maybe I need a small amount of heat)

Thanks.
