Renaissance Metal De-Corroder


[] Renaissance Metal De-Corroder is an amine complex of hydro-oxycarboxilic acid in an aqueous solution. It has a slight acidic pH at 4.0

It was described by the manufacturer for treatment of iron; copper; copper alloys; brass; steel; zinc; and galvanized materials with corrosion.

The effect from De-Corroder was rupture bonds between a base metal and the corrosion layer that forms a sludge. This sludge can be cleared by wiping or brush, then rinsed with water.

Manufacturer claims that the complex is safe for prolonged exposure and metals would be stable for up to 14 days, prior to a protective coating.


Manufacturer suggests that De-Corroder is most effective between 10-20C.
