Gram staining is one of the most significant staining techniques in microbiology. Gram′s decolouriser solution is a mixture of ethanol and acetone. Gram′s decolouriser solution is used in Gram staining procedure, after the iodine step to remove the crystal violet dye. The decolouriser dissolves the lipid layer from the gram-negative cells.

Gram’s safranin solution, also known as Safranin T or Basic Red 2, is a ready-to-use staining solution that comprises 10% safranin in ethanol. Safranin is a basic, cationic, azine dye containing a planar, diaminophenazine chromophore, with a phenyl substituent attached to a ring nitrogen. The trimethyl cationic form of safranine is lipophilic, whereas the dimethyl forms are weakly hydrophilic. It is most notably used in bacteriology as a counterstain in Gram staining to differentiate between Gram-positive and Gram-negative bacteria.

Gram’s crystal violet solution, also known as gentian violet or hexamethyl pararosaniline, is a basic, cationic, acidotropic aminoarylmethane dye. It is a hexa-N-methylated triaminotriphenylmethane with a moderately sized lipophilic cation and a slightly nonplanar conjugated system. It is used in bacteriology as the primary stain in Gram staining to differentiate Gram-positive and Gram-negative bacteria. It is known to possess antibacterial and antifungal properties.
