Ardrox ARDROX-1218 (20-Ltr-Drum)

ARDROX® 1218

Overview

ARDROX® 1218 is an inhibited acid rust and scale remover formulated from phosphoric acid and proprietary corrosion inhibitors. It is designed to effectively remove rust, heat-treatment scale, welding scale, and corrosion products from ferrous metals, while also being suitable for use on aluminium, copper, and zinc alloys. The product is particularly valuable where dimensional accuracy and close tolerances must be maintained, including chromium-plated ferrous components used in aerospace and precision engineering applications.
