Cleaning method including use of solid particles
First Claim
1. A method for cleaning at least one soiled substrate in a rotatably mounted cylindrical drum of a cleaning apparatus, the method comprising:
- rotating the drum such that said at least one soiled substrate describes an annular path whereby a central portion of the drum is not occupied by any soiled substrate and introducing a multiplicity of solid particles into said central portion of the drum, wherein the method comprises operating the cleaning apparatus for a wash cycle wherein during said wash cycle the drum is caused to rotate such that said at least one soiled substrate describes an annular path whereby said central portion of the drum is not occupied by any soiled substrate for a first period and wherein the drum is further caused to rotate such that said at least one soiled substrate does not describe an annular path for a second period, and wherein said drum is caused to rotate at a G force of at least 1 for said first period, and further wherein said drum is caused to rotate at a G force of less than 1 for said second period.

Abstract
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.
