Distilled water is used after applying alcohol in a Gram stain to stop the decolorization process. Alcohol removes the primary stain from Gram-negative bacteria, making it important to quickly rinse with distilled water to prevent further removal of the crystal violet stain from Gram-positive bacteria.
