Residue that accumulates on metallic molding surfaces during repeated molding of plastics such as PVC can be removed by cleaning with an aqueous solution of a glycol or oligo-glycol monoether, an amine, and a chelating agent. The cleaner is sufficiently effective to replace mechanical blasting that was previously required.

Les résidus s'accumulant sur des surfaces métalliques de moulage lors du moulage répété de matières plastiques comme le PVC peuvent être éliminés par nettoyage à l'aide d'une solution aqueuse de glycol ou de monoéther d'oligo-glycol, d'amine et d'un agent chélateur. Le nettoyeur est assez efficace pour pouvoir remplacer l'abrasion mécanique requise antérieurement.
