Zerust® Corrosion Removers
Zerust’s Axxaclean™ rust and tarnish removers are powerful solutions for the rework and recovery of metal items. Zerust offers a range of technologies, from pH neutral products to more aggressive products that also inhibit flash corrosion on cleaned surfaces.
Axxaclean™ ICT®620-RR: Light to Medium Rust Remover

Zerust 620-RR is a pH neutral dip that removes rust, even in crevices, pits, and threads. It replaces labor-intensive abrasive cleaning that damages surfaces. The product works by breaking the chemical bond of rust and does not harm any other metals and non-metals. Surface may be darkened with carbon residue after cleaning. Cleaned parts must by protected to prevent flash rusting.
Axxaclean 2048: Light to Medium Rust and Tarnish Remover

This is a fast acting rust and tarnish remover. It removes light to medium rust and tarnish, even in cracks and crevices. It is mildly acidic (about 2.5 pH) similar to a soda drink. It cleans and deoxidizes ferrous metals, brass, copper and various alloys without leaving a gray residue. Provides immediate protection from flash rust or re-tarnishing for several days in controlled environment. It may be applied by immersion, brush, or spray.

It is non-foaming and can be applied by immersion, high-pressure or ultra high-pressure wash.

- Rinse the parts with de-ionized water and inspect.
- Wipe parts with a dry cloth if needed (some black carbon residue may remain on the metal surface).
- Repeat soaking if rust remains, and re-rinse.
- Air dry. Check for areas where solution may have pooled, re-rinse and dry.
