Invisible Stain?
Isn't That An Oxymoron?
It sounds impossible, but there is such a thing as an invisible stain. These kinds of stains are a particular challenge to drycleaners because they usually don't show themselves until after the garment has been cleaned.
According to the National Center for Garment Analysis, these stains are difficult to remove because they have had the time to 'set'. When the spill or mishap initially happens, it appears not to have left a stain. Understandably, the consumer forgets about the incident and doesn't bring the garment in for cleaning quickly. In the meantime, atmospheric conditions cause the stain to oxidize, much the same way an apple that has been cut open turns brown when exposed to the air.
After cleaning, the stain clearly manifests itself, and voila!, I have to explain to a valued customer that we didn't put the stain on their garment. This is never an easy thing to do.
I guess the lesson to be learned from this, is for you to be aware of any spilled coffee, tea and other stains. Even if you don't see a stain, bring the garment in for cleaning promptly. It would also be helpful if you let us know that there was a mishap. Our chances for successful stain removal are increased the sooner we have the opportunity to begin the correction process.
