A method of removing cooked-, baked-, or burnt-on food soil from cookware and tableware comprising washing the cookware/tableware in an automatic dishwashing machine in the presence of an organic solvent system having a volatile organic content of less than about 50 % by weight and a wash liquor concentration of from about 100 ppm to about 10000 ppm. The method includes the storage and delivery of organic solvent compositions and dishwashing detergent composition from multi-compartment containers.
