I hadn't heard of vacuum drying electronics after water submersion -
interesting - hadn't thought of that.

With any electronic device that gets water dunked, it's important to remove
batteries as soon as possible. This will help prevent corrosion due to
electrolysis of circuit board traces and components. Then submerge the
device in distilled water (insulator) to rinse out and dilute as much of the
mineral laden water (conductor) as possible - - then dry.

Options for drying might be putting item on open oven door with oven on low,
or putting item in sun etc. Don't overheat and don't power-up the item until
totally dry.
