Also known as isopropanol. At high concentrations (>90%), it makes an excellent general-purpose solvent for electronics repair, as it does not promote corrosion and dries without leaving any harmful residue.
Isopropyl alcohol is sometimes referred to as rubbing alcohol, although this term should be used with caution as it can also refer to ethanol-based alcohols that are not suitable for electronics repair.
Isopropyl alcohol has a variety of uses in electronics repair, including removing oils and contaminants from electrical contacts, removing corrosion after liquid damage, cleaning up spills, and wiping away old thermal compound. 90% or higher solutions are safe to use on most printed circuit boards, since they dry quickly and don't leave behind any residue. Isopropyl alcohol also works well as a solvent for many adhesives, and for cleaning and prepping the surface before new adhesive is applied.
Isopropyl alcohol is flammable and is also a skin irritant, and should therefore be used with appropriate caution.
