A method to remove stubborn stains from carpets and textiles that includes the application of an ammonium salt in combination with an oxidant and a fluorinated alkyl sulfonic acid or its salt. A major advantage of the method is that the solution is strong enough to remove coffee and tea stains yet sufficiently mild that it does not damage the carpet.
Procédé destiné à enlever les taches rebelles sur les moquettes et les textiles comprenant l'application d'un sel d'ammonium combiné à un oxydant et à un acide sulfonique d'alkyle fluoré. Le gros avantage de ce procédé est que ladite solution est suffisamment forte pour enlever les taches de café et de thé, et cependant suffisamment douce pour ne pas endommager la moquette.
