Pharmaceutical Drug Residue Contamination

Pharmaceutical-residue contamination, it arises from active ingredient deposits during equipment processing. This residue, it forms sticky layers and differs from mineral scales by organic stickiness that bonds deeply. On stainless steel and glass, it clings unevenly and defies solvents, so removal challenges persist; laser cleaning, it vaporizes residue selectively and leaves surfaces intact.
