In Gomori Methenamine Silver staining, which practice helps prevent under-oxidation that causes faint staining?

In Gomori Methenamine Silver staining, the crucial step is oxidizing tissue carbohydrates to create aldehyde sites that will react with the silver developer. If oxidation is incomplete, there are fewer aldehyde groups to bind silver, leading to faint staining. Extending the oxidation time increases the formation of these aldehyde sites, which promotes more silver deposition and strengthens the stain. Other adjustments, like longer staining, hotter silver solution, or longer toning, don’t fix the underlying lack of oxidation and can affect background or color in different ways without solving the faintness caused by under-oxidation.
