PH NEUTRAL DERUSTER COMPOSITION

摘要

The present invention relates to a deruster composition of neutral pH which is designed to remove corroded metal from metal surfaces. The deruster composition can be used to remove rust or tarnish, and can also be referred to as a metal brightener. The deruster composition has a pH in the range of 5 to 8, where the composition comprises: water; at least one surfactant and at least one chelating agent; where at least one surfactant is an alkyl polyglycoside and at least one chelating agent is an aminopolycarboxylic acid. The ability to operate within a neutral pH range reduces damage to the metal during cleaning. In addition, hazards to operating personnel are minimised.
