Again untrue whatever you think is “whole” water, any dessicant will absolutely 100% help with evaporation.

Not every person is tech savvy enough to open boards. Advice for most novices is still put phone between dessicant to get water out if the device is valid and good advice.

Would using isopropyl alcohol be better option? Sure it is. but telling my aunt to do it, and device will probably die because she doesn’t know how to handle pcbs anyway. I’d much rather just advice using dessicant and hope mineral residue doesn’t sort anything. And I’ll continue with that advice forever.
