Next up, open all access panels, ports etc and put the device in a warm airflow - not too hot to avoid distorting the plastic - and let it sit there for at least a day, preferably longer.
Water wasn't designed to get in easily and it won't be dried out easily either - don't rush the process. I'd give it a couple of days over a warm air register.
Airflow is important - a radiator has heat but not enough airflow, in my opinion.
Do all that before powering the device up again.
The bag of rice helps as well. Saved several cell phones with that.
