Isopropyl Alcohol, also known as Isopropanol, IPA, or 2-Propanol, is the most used solvent for cleaning electronics. It is a polar protic solvent, so it can be used to clean ionic residues, and it is good at dissolving both polar and non-polar residues. It is safe on most painted surfaces, plastics, and elastomers. It leaves no residue, evaporates quickly relative to water, and does not cause corrosion. It is low toxicity compared to alternative solvents and is similarly relatively environmentally benign, being ozone safe with excellent “green solvent” scores.
