摘要： A bleaching product and a method of removing soils from fabrics by contacting the fabrics in an aqueous wash solution with a product comprising a peracid precursor, a source of hydrogen peroxide and a source for delayed release of an acid into the wash solution to initially permit effective in situ formation of peracid, the acid thereafter reducing the pH of the wash solution for enhancing bleach performance of the peracid. The source of the acid may be included in the bleaching product, for example, as an acid of delayed solubility, an acid coated with a low solubility agent or an acid generating species, or independent of the bleaching product. The acid source is selected to be compatible with the peracid or precursor and adjuncts. The method for removing soils thus comprises contacting the fabrics in an aqeuous solution with a peracid precursor and a source of hydrogen peroxide, initially raising the pH of the solution for effective in situ formation of peracid and then reducing the pH for enhancing bleach performance of the peracid.

摘要： The invention provides a cleaning method in which a solvent such as densified carbon dioxide can be used for rapid and efficient cleaning, but with decreased damage to solid components such as buttons. The method comprises contacting a substrate to be cleaned with a first fluid, removing the first fluid from contact with the substrate while replacing with a second fluid, and recovering the substrate substantially free of the first and second fluids and from the contaminant. The first fluid is a densified gas while the second fluid is a compressed gas. A preferred embodiment of the method includes the use of a pretreatment designed for compatibility with the densified first fluid.
