How to repair Sony XPlod Radio buttons

UPDATE 6/10/2019:

The button problem appeared again after a while, however this time i was able to see the radio trying to seek for a station, it seems that the Seek+ button was giving problems, i removed it from the PCB board and the radio is fine since.

This is a Sony Xplod 52wx4 radio that had some buttons not working. After trying reset the radio and check for stuck buttons the problem remains. So i try to clean out the buttons to neutralize some moisture in them, and that seems to do the trick. I used alcohol to help the cleaning process, so you do not need to do the first hair dry like i did in the video ;)
