    • Enhanced cleaning can be obtained by applying primarily to a stained region of a washable soft substrate a prespotting composition that contains at least one molybdate and which can generate singlet oxygen in situ in the presence of a peroxide, optionally applying to the substrate a prespotting composition that contains at least one peroxide, and rinsing, laundering or otherwise cleaning the substrate, using a peroxygen-containing built detergent to clean the substrate if a prespotting composition containing peroxide has not been applied to the substrate. Preferred embodiments of the method can provide stain removal comparable to that obtained using chlorine bleach but with better color safety. The method preferably is performed using a prespotting kit containing a molybdate solution, a peroxide solution and instructions for applying the solutions primarily to a stained region of a washable soft substrate, thereby providing a treated article whose stained region has preferentially absorbed thereon an aqueous singlet oxygen-generating mixture comprising peroxide and molybdate.
    • 可以通过主要应用于含有至少一种钼酸盐并可在过氧化物存在下原位产生单线态氧的预喷射组合物,主要应用于可洗涤柔性基质的染色区域,任选地向基材施加预喷涂组合物, 含有至少一种过氧化物,并且如果含有过氧化物的预先投配组合物未施加到基底上,则使用含过氧的内置洗涤剂来清洗,洗涤或以其他方式清洁基底。 该方法的优选实施方案可以提供与使用氯漂白剂获得的污渍去除相当的,但具有更好的颜色安全性。 该方法优选使用包含钼酸盐溶液,过氧化物溶液的预先投药试剂盒和用于将溶液主要施用于可洗涤软质基材的染色区域的说明书,从而提供其染色区域优先吸收水溶性单线态氧的处理制品 包含过氧化物和钼酸盐的生成混合物。
