Water damage, but now temperature warning - what next?

My Son had a tumble while carrying a backpack containing of all things 1 litre of juice, and his iPhone 4 A1332 model.

Due to the backpack being waterproof, and the bottle of juice getting smashed the iPhone was left submerged for a few minutes while we sorted him out.

I stripped the back from the phone, disconnected the battery and left it to dry. I got a thirsty bag on order and never touched the phone for 2 weeks.

After re-assembling the phone, everything seems to run fine for about 5-10 minutes then it warns of temperature and the phone needs to cool down. If you don't turn it off it runs slower and slower until it hangs.

I've disconnected the battery again and put it back in the thirsty bag.

So - am I right in thinking due to the sugar in the juice, even though the phone has probably dried, the sugar remains on some surfaces, causing over-heating and/or sensor errors?

What would the next step be? I've seen mention of ISO Alcohol (95%+) - however do I submerge the phone in this, or strip it right down and clean each part individually?

It's become a bit of a project now. I've bought the iFixit tools and repair book, and having worked on PCs years ago already have the ESD mat and wrist strap.

Any advice and pointers really appreciated.

Thanks.

Disassemble it and clean all parts with 90%+ isopropyl alcohol. If you are dealing with a sugary substance, you can preclean everything with sterile water. Then clean it with the isopropyl alcohol and a soft brush. Check for any missing, burned/charred components. Once properly cleaned, replace the battery and then re-evaluate.

I think any damaged that is caused is most likly done now as you have left it ..

But get iOS alcohol and strip the phone til the motherboard and take off all shields to expose the components .

Now get a plastic tray to submerge the motherboard in and with a toothbrush with soft bristles clean down the board after that use air line to blow access alcohol off then leave 24hours to dry.. Then install

Thanks for the replies. I'll strip it down and soak the motherboard in Isopropyl Alcohol.

I'll order some Sterile water and 99.9% Isopropyl Alcohol in the morning.
