ABSTRACT
The conventional methods of rust removal involve acid cleaning or sandblasting. These techniques, though proven to be effective, can be environmentally hazardous. Some new derusting techniques, such as use of rust neutralizers converts rust into a chemically neutral surface, leaving the surface ready for coating application. However, the use of these neutralizers is limited to oil-based types only, and the chemicals contained in these products can be detrimental to the worker's health.
