You can see why such a stain was missed. And you can see how much you can assist the drycleaning by pointing out any spillage, no matter how small it is. This espcially true with natural fibers such as silk or wool and their blends. These garments present the more difficult problems in removal of fruit juices and other beverage stains. Most beverages, including coffee and tea, can disappear after the stained area is sponged, but removal of all the staining substance is usually incomplete, especially on a heavy wool fabric.
Some people perspire more heavily than others and have greater problems.
This problem is particulary pronounced in silk and wool. Perspiration left in a silk garment can actually cause deterioration of the silk fibers. Repeated wearing of a silk or wool blouse or jacket with continual soiling from perpiration and body oils can develop into a permanent yellow discoloration and an objectionable odor. People who perspire heavily need to have their clothes cleaned more frequently. Point out any perspiration problems to your drycleaner when you leave the article for cleaning.
