Process for denaturating water dilutable paints and solvent-based paints, wherein said paints are treated by washing with the assistance of an aqueous denaturation phase whose pH is from 4.5 to 7 and preferably from 5 to 6 and which contains an effective quantity of at least one denaturation agent consisting of an amine molecule of formula (see fig. I) or of formula: (see fig. II) in which the substituents R1 to R7, which may be identical or different, represent: - a hydrogen atom, - a radical of formula -O-Re in which Re is chosen from the group comprising hydrogen and a C1 to C4 saturated aliphatic hydrocarbon chain, it being understood that the substituents R5 to R7 are not simultaneously all hydrogen atoms, or of a hydrate or else of a salt of an organic or inorganic acid salt of said amine molecule, preferably a salt of sulfuric acid, phosphoric acid or hydrochloric acid.
