Spill Hero Base/Alkaline/Caustic Neutralizing Absorbent is a unique blend of citric acid and super absorbent material that has been specifically formulated for safe and effective control of basic, or alkaline, spills. Spill Hero encapsulates these spills quickly, neutralizing bases and reducing emission of toxic fumes. Spill Hero is ideal for absorbing spills that contain chemicals such as sodium hydroxide (lye), potassium hydroxide (caustic potash), and calcium hydroxide (lime). Once absorbed, it will not leach the toxic liquids and cause harm to the environment. Spill Hero meets or exceeds all governmental regulations for proper landfill disposal. Spill Hero Base/Alkaline/Caustic Neutralizing Absorbent is great for homes, as well as laboratories and other commercial businesses that handle bases. *Not for use with hydrofluoric acid.
