ABSTRACT:
A process for decontaminating textiles contaminated by bacteria comprising washing said textiles with a detergent composition free of any peroxide bleaching agent, and then treating said textiles with a peroxide bleaching agent in an aqueous bath at a pH of between about 9 and 13, at a temperature of between about 40.degree. to 70.degree. C., in the presence of calcium, for a time sufficient to decontaminate said textiles; said calcium rendered soluble and uncomplexed and being present in an amount between about 0.001 to 1% by weight based on the weight of the bath with the source of calcium being selected from calcium oxide, calcium hydroxide, or a calcium salt whose anion is inert with respect to the peroxide bleaching agent and whose dissociation constant is above about 0.01.
