Title:

Water Damaged, Logic Board Repair - EMI Shield Removal?

Text:

I have an iPhone 5 that was dropped in the toilet. I disassembled it, scrubbed it with a toothbrush + isopropyl alcohol (91%).  I have also replaced the battery, and tested a known working battery. I have since reassembled and it is in a boot loop on the initial apple icon logo.

I have reason to believe that the logic board has water damaged parts under the EMI shield.

My Question is what is the best way to remove the EMI shielding? Solder Gun, Heat Gun etc? or if I am best just leaving the motherboard in the isopropyl for a day and crossing my fingers that it breaks down the corrosion enough that I can just use a can of air to get it out.
