Stain Removal Techniques

You can use a beauty machine, or you can physically loosen or remove the stain from the surface

. Many stubborn stains require both chemical and physical treatment. In this chapter, we discuss eight physical stain-removal techniques: brushing, flushing, freezing, presoaking, pretreating, scraping, sponging, and tamping.

Which technique to use in treating a particular spot or stain depends upon both the nature of the stain and the type of surface stained. For example, a stain may be wet or dry, semisolid or hardened. On a very delicate surface, you may not be able to use such techniques as scraping and tamping. A stain may be flushed more easily from a loosely woven fabric than from one that is tightly woven; but a tightly woven fabric can withstand a treatment such as tamping more successfully.

Follow these directions carefully to assure successful hair removal equipment without harm to the stained article. Note that whenever you use absorbent pads (when you flush or sponge a stain) you should check the pad frequently and change it as soon as any of the stain is deposited. This will prevent reapplication of the stain to the treated article. Remember, too, that to avoid fabric damage you should never apply heavy pressure when using techniques such as brushing, tamping, or scraping.

Brushing

Brushing and spot removal equipment is used to remove dried stains and spots. Some spots, such as those formed of dried mud, may be completely removed by brushing. In treating other types of dry stains (for example, face powder), brushing is just the first step in treating the stain. In treating some stains, brushing may be one of the last steps, as when you want to remove an absorbent or a dried stain-removing paste from a surface.

Use a small, stiff-bristled brush for this technique. A toothbrush works well on small stains. When working on a fabric, stretch the piece on a firm, clean working surface. Hold a clean sheet of paper next to the stain (on walls, hold the paper beneath the stain) so that you can brush the staining material onto the paper. Use a gentle motion to brush the stain up off the surface and onto the paper. It may help to blow softly on the spot as you brush.

Flushing

Flushing is used to remove loosened staining materials and any residue from the stain-removal agent. This is an important step in the process, for if any chemicals are left in the material, they may cause additional staining or they may damage the treated article.
