Summary:Methods for cleaning at least one soiled substrate in a rotatably mounted cylindrical drum of a cleaning apparatus with a multiplicity of solid particles are provided. One method includes the steps of: agitating the at least one soiled substrate in the drum with wash liquor and the multiplicity of solid particles for a first cleaning cycle wherein the wash liquor includes at least one cleaning agent; draining the wash liquor from the cleaning apparatus; and introducing an aqueous non-detergent medium into the cleaning apparatus and agitating the at least one soiled substrate with the multiplicity of solid particles in the drum for a second cleaning cycle. Another method includes rotating the drum such that the at least one soiled substrate moves about a generally circular path and introducing the multiplicity of solid particles into the drum through an annulus defined by the generally circular path as the drum rotates.
