My job mainly consist of commisioning surface treatment machines (aka galvanotechnic machines). These have a lot of chemical products stuff involved in, which are put into big open deposits.
Since six years, I "have accidentally put" two phones into:
- Demineralised water (it was easy to recover because it is a transparent liquid). It worked after the soak.
- Cupper Sulphate: It is an "electric blue" type of fluid. When it slipped down of my chest pocket its associated rectifier was working at 10 Volt and 1500 Ampere. I recovered it and worked.
Other of my mates have (again, accidentally) put cellulars into 85% Sulphuric Acid solution, anodising sealing, nickel, etc. Some of the mobile phones were recovered, another not. Some worked again, another not.
Cheers.
