Isopropyl alcohol (IPA) is one type of solution it is used for cleaning printed circuit boards (PCBs). It has some main advantages:

1. It’s cheap
2. IPA displaces water well, allowing surfaces to dry
3. It removes ionic contamination. During water lock in mobile it will help more(we already uploaded how to fix water locked mobile like a professional)
4. IPA has been used to remove flux residues soldering and as a general cleaner to remove oil, grease, and other handling soils.
5. Use a concentration higher than 70% for effective results

Proper IPA Storage

IPA storage conditions required to restrict its exposure to moisture, until the moment of delivery for cleaning, also presents a problem.

IPA is usually purchased in large bulk containers (bottles, cans, or drums), same time IPA not placed in a sealed container for use, because if you left exposed to the open air, it collects water vapour even faster.
