Derusting Chemical - Derusting chemicals are used to remove rust (iron oxide) from metal surfaces. These chemicals work by dissolving or converting rust into a more stable compound that can be easily cleaned off. Here are some common types of derusting chemicals: 1. Acid-Based Derusting Chemicals Phosphoric Acid – Converts rust into iron phosphate, which can act as a primer. Hydrochloric Acid (Muriatic Acid) – Strong acid that dissolves rust quickly but can be aggressive on metals. Sulfuric Acid – Powerful but can be dangerous if not handled properly. 2. Chelating Agents (Eco-Friendly) EDTA (Ethylenediaminetetraacetic Acid) – Binds with rust and removes it without harming the metal. Citric Acid – Mild, safer, and commonly used for household rust removal. # Derusting Chemical Manufacturer.
