many people believe that all marks or stains can be removed by dry cleaning. not every stain can be cleaned just by dry cleaning. some need to be treated with spotting solvents; sometimes by steam jet or by soaking in special stain remover liquids before garments are washed or dry cleaned. also, garments stored in soiled condition for a long time are difficult to bring back to their original color and texture. natural fibers such as wool, cotton, and silk of lighter colors should not be left in dirty or soiled condition for long amounts of time as they absorb dirt in their texture and are unlikely to be restored to their original color and finish.
