Tannin Formula

Coffee Stain

Q: I just prespotted a small coffee stain on a white linen blouse with tannin formula and then drycleaned it normally with a light colored load. When the blouse came out of the drycleaning machine the coffee was gone, but there was a large greyish tan discoloration in the area. I think the brightener broke down from the tannin formula. What can I do to fix this problem?

A: It is not very likely that tannin formula caused any damage to the fabric whitening agents as you may believe. Most likely, this is local soil redeposition which can occur readily on linen as well as other cellulose (plant type) fabrics when portions of the garment are prespotted with wetside agents and then drycleaned while these areas are still damp. Cellulose is absorbent by nature, especially when wet, so all moisture must be allowed to dry out of the fabric prior to cleaning. Otherwise, local redeposition from floating soils and impurities in the load may result, causing grey or tan stains. Many times, soaking a cellulose garment in a detergent and warm water bath followed by thorough rinsing and air drying will remove the discoloration and restore the garment. Local spotting may be sufficient for a small area.
