Abstract
The scale formed by use of alkaline salt-based cleaners and which comprises one or more alkaline salts and organic scale is removed by applying an aqueous solution comprising alkali metal carbonate salts and optionally, a hydrotrope to remove the organic scale. A mixture of potassium and sodium carbonate salts has been found to effect better descaling than use of either of the salts alone.
