It is the most common method of endospore staining, which makes the use of three reagents, namely primary stain, decolourizer and counterstain. Malachite Green is also compatible with Kordon's NovAqua and Fish Protector . Malachite green can also directly stain endospores within cells; here a safranin counterstain is often used. The slide was allowed to cool. This is because, during smearing and heat fixing, the malachite green penetrates into the endospore with the help of the heat from the steam, and during the water-rinse, the dye is not easily washed away.

The alternative staining used is Methylene Blue solution (0,5 %, 0,7%, Gently heat the slide over flame until vapors appear. Malachite green is water soluble and has a low affinity for cellular material, so vegetative cells may be decolourized with water. Washing with water decolorizes the cell, but the endospore retains the green stain. Then, the use of heat helps to penetrate the primary stain to the endospore.
