摘要： An improved solvent cleaning process of cleaning a non-aqueous solvent used in a dry cleaning process for fabrics including consecutive wash cycles for washing respective fabrics batches, including a basic solvent refining cycle and a first advanced solvent refining cycle, the basic solvent refining cycle including a step of separating solvent into a first solvent fraction and a second solvent fraction which is less clean than the first fraction, wherein the basic and first advanced solvent refining cycles are independently effected when solvent to be cleaned fulfils a respective predetermined condition.
