Aqua regia is one thing, great for inorganic contaminants and quite good for organics. But if you want ultimate cleanliness from organic contaminants, you want what’s called piranha solution – h2s04 and 30% hydrogen peroxide. It fits the name and has fascinating chemistry such as the production of atomic oxygen as active cleaning agent.
