CLEANING OR DE-GREASING OF METALLIC MATERIAL BY CHEMICAL METHODS OTHER THAN ELECTROLYSIS

**Definition:** This place covers:

Methods, compositions and apparatus for stripping non-metallic inorganic coatings from metallic substrates.

**Glossary:** - Metallic material: covers metals and alloys - Pickling of metallic material: Chemical removal or dissolution of surface deposits of inorganic contaminants, such as rust (iron oxides), or scale from ferrous metals, copper or aluminium alloys, or corrosion products from metallic surfaces. Chemical stripping of non-metallic inorganic coatings from metallic substrates. - De-greasing of metallic material: Non-mechanical removal or dissolution of surface deposits of organic contaminants, such as oils, fats, greases, dust, finger-print contaminations, or similar hydrophobic compounds from metallic surfaces.
