Abstract

A process for the removal of stains from textile fabrics comprises soaking the fabrics first in a low-pH aqueous liquor containing, for example, citric acid and sodium citrate, then subsequently in a bleaching liquor, for example, containing a dichlorocyanurate bleach, then rinsing and drying the fabrics. The first aqueous liquor preferably contains an oxidising agent, for example, potassium iodate, to mask and/or neutralise sulphurous odours. The process may suitably be carried out by hand. The product comprises two separately packaged particulate compositions for generating the two liquors; these are preferably packed in visually distinct sachets within common outer packaging.
