CONCORD, N.C. — A reader recently sent me an e-mail that contained several questions. I’ve decided that I’m going to use it as the basis of this month’s column, because the problems cited are common to many operations and my comments should provide guidance and options in your stain-removal efforts.
Q: I use _____ as my POG and lately it’s been leaving a chemical stain (ring) on the clothing that I dry clean…
A: Most paint, oil and grease removers (POG) should easily flush in the drycleaning system. The vast majority of POG can be divided into those that are based in alcohol and others that have an “oily” base (OTPR). It is important to know the contents of any chemical stain-removal agent, as some combinations of fiber, fabric and dye are extremely sensitive to the alcohol (pH).
When used on the dry side, POG is effective on chemically soluble stains such as cosmetics, paint and grease as well as aiding in the removal of difficult solvent-soluble stains. POG is generally ineffective on water-soluble stains.
