Product Introduction

The acidic rust‑removal and cleaning agent employs a composite organic acid formulation, with corrosion inhibitors and penetrants added, specifically developed to address oxide scale, rust, and yellow staining on metal surfaces.
It delivers highly effective rust removal while protecting the substrate, making it suitable for descaling carbon steel, cast iron, and other ferrous metals.

Instructions for Use

Concentration ratio: Dilute at 8–20% (15–20% for heavy rust, 8–12% for light rust);
Washing temperature: Room temperature to 60°C; optimal range: 40–50°C.
Cleaning method: Primarily use soaking, for 5 to 30 minutes, with the duration adjusted according to the degree of rust. After cleaning, rinse thoroughly with clean water 2 to 3 times, then proceed with drying and rust‑preventive treatment.
Precautions: Wear acid-resistant gloves and safety goggles, and ensure adequate ventilation during handling.

Application

Mechanical maintenance: refurbishment of used equipment and rust removal from components.

Hardware manufacturing: Removal of oxide scale from carbon steel workpieces after stamping.

Steel Structures: Small steel structural components and pipeline derusting pre‑treatment.

Automotive parts: Rust removal and cleaning of cast iron and carbon steel components.
