Piranha solution Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (HSO) and hydrogen peroxide (HO), used to clean organic residues off substrates. Because the mixture is a strong oxidizing agent, it will remove most organic matter, and it will also hydroxylate most surfaces (add OH groups), making them highly hydrophilic (water-compatible).
