You need to open it up and clean it again using the Isopropyl Alcohol.
Using 99%+ IPA is best because there are no additives which may be in some Isopropyl Alcohols having a lesser percentage of alcohol, but if you can’t get any then 70% is better than nothing. Also 99%+ IPA leaves no conductive residues once it has evaporated. Like nearly all liquids except distilled water it will also conduct electricity until it has evaporated away, so make sure that the battery is disconnected before cleaning

You need to gently ''brush away any corrosion'' using a soft brush moistened with the alcohol. It’s the brushing that removes the corrosion and the alcohol ensures that it is electrically “clean” afterwards. Brush gently as you don’t want to remove any components from the board. If you have an ultrasonic bath you could immerse the board in it in a solution of IPA and the cavitation bubbles produced in the bath by the ultrasonic pulses do the cleaning. You don’t want it to be too vigorous though ;-)

The device has to be dis-assembled so that all the components can be checked for moisture and corrosion. This means also removing any metal shields that may be covering some components as the water may have got in under the shield and also unplugging any cables so that the cable ends can be cleaned and also the connectors that they were plugged into.
Once you are satisfied that it is as clean as you can get it and that it has been all re-assembled properly then reconnect the battery and test if it all works.
Also using rice to fix the problem is a myth. It does nothing to fix the problems caused by corrosion.

You need to gently ''brush away any corrosion'' using a soft brush and the alcohol after you have either immersed the board or poured the alcohol over it, as the alcohol only displaces the water, it doesn’t remove any corrosion that may have occurred.
