After drycleaning, my customer’s pale pink drapes had yellow streaks. I tried re-cleaning in clear solvent, but this process did not improve the appearance. What happened, and how can I prevent it? A:
Yellow streaking of this type results from an accumulation of atmospheric soils, fumes, and light exposure on the exposed folds. This type of discoloration generally is not removed in normal drycleaning procedures. It may be more prominent after cleaning when some of the masking soils are removed.
Wetcleaning procedures may be necessary to remove the soils and the yellowing. But potential shrinkage, color loss, and texture change may occur. Wetcleaning may not restore color changes due to atmospheric fumes or gases or light fading.
For more information on this sort of damage, please see TABS 394 on DLI's Encyclopedia of Drycleaning Online.
