  • Such manually applied agitation provides a mechanical action which acts to physically break up the stain. This is particularly useful for stains which have been left untreated for an extended period of time, i.e., days, weeks, and longer periods, and may have hardened.
  • Such manual agitation provides in addition to the mechanical loosening of the stain, further acts to improve the penetration of the spot pretreatment composition throughout and among the stained fibers. Such mechanical action also improves the overall stain removal characteristics of the spot pretreatment composition. Due to these beneficial characteristics, containers having a liquid permeable applicator tip or end is particularly preferred, and such containers are known to the art.
  • a soiled garment is treated by applying an effective amount of the spot pretreatment composition directly at the location of a stain and optionally onto the surrounding area of the stain, and subsequent to such application, a disposable absorbent sheet, or another part of the garment or other garment to manually agitate and "rub in” the spot pretreatment composition so to ensure that it is thoroughly distributed amongst the stain and the fibers at the locus of the stain.

  • These sheets when used, may be of any dimension but are preferably sheets having an area of at least two square centimeters but are preferably ones having greater areas. Sheets having larger areas, i.e., those having areas of at least 50 square centimeters and greater are preferred from the view point of ease of use and handling.
