Water-based concentrate containing 47% phosphoric acid for removing rust, limescale and oxide layers, and cleaning metal surfaces (iron, steel, copper, brass, aluminium). Contains corrosion inhibitors. The product complies with specification Mil-C-10578 (Type III).

Heavy rust and limescale (ferrous metals): dilute with water at 1:3; soak for 20 minutes to 1 hour. Heavy corrosion (non-ferrous metals): dilute with water at 1:7–1:10; soak for 20 minutes to 1 hour.

Use a brush, paintbrush, etc. Heating the solution (up to max. +65°C) improves cleaning performance. Rinse treated surfaces with clean water and protect them with a corrosion inhibitor.
