[ADGM1304] Cleaning ADGM1304 switch PCB with IPA

Hello,

I would like to clean my PCB with IPA (Iso-Propyl Alcohol) after soldering, since leakage currents at RFx & RFC pins are higher. Is it safe to clean the PCB by dipping in IPA ?.  I am asking this because i am worried, whether moisture might enter the hermetically sealed package and damage the switch.

Regards,

Siva.
