Abstract
A process for removing hematoxylin precipitate from a surface of an automated hematoxylin stainer, systems adapted for performing such processes. The process and systems use a hematein precipitate removal solution having a pH in the range of between about 8.9 and 10.5 and including a liquid oxidizing component and alkaline component. The hematein precipitate removal solution is placed in contact with a surface of the automated hematoxylin stainer, thereby dissolving any hematein precipitate deposited thereon.
