Turn it off. Do not charge it. Skip the rice.

Liquid can sit quietly and corrode later. The useful history is what liquid, how long ago, whether it was charged afterward, and whether the files matter more than the device.

If the files matter most Request an evaluation

Do

Power it down if you can do that safely. Bring it in. Mention any previous repair.

Do not

Do not charge, heat, shake, or bury it in rice. Do not keep testing it to see if it is fine.

Liquid-damage work is an evaluation. Repair and data recovery are not guaranteed.
