Determining the type of stains

Determining the type of stains it causes great difficulties therefore, that they rarely exist in a homogeneous form. For example, street dirt contains both dust, as well as fatty substances, and grease stains are caused by the action of many different substances. Grease stains are always darker than their surroundings, moreover, they have indistinct edges.

Contaminated grease stains, e.g.. car grease or tar stains, they are brown or black and oily, sticky surface. Sometimes stains that only appear on the surface of the fabric, not penetrating into it, they give the impression of dirt and dust, when in fact they were caused by the contact of the fabric with other substances. In such cases, try to carefully scrape the stain off the surface of the fabric - it will then be easier to determine the cause of the stain. Also, before removing large wax or stearin stains, remove the top layer of the stain with an appropriate stain remover., scraping it off gently, without damaging the surface of the fabric.

The source of color stains may be fruit juice, lipstick for lips, nail polish or paint. Dried stains are difficult to remove, because they have a hardened shell on the surface. Ink or pen stains can be recognized relatively easily. On the other hand, it is extremely difficult to identify the causes of dull, yellowish or brown spots, the so-called. oxidized (oxidation) on fabrics that have been washed several times. These may be fruit juice stains, cocoa, red wine or rust. When someone rubs against damp iron in bright clothing, brown spots appear after some time and are usually difficult to visualize, under what circumstances did this happen. Metal buttons are also the cause of rust stains, buckles, haftki, pins and safety pins attached to clothing. It's worth adding, that carelessly removed blood stains leave traces similar to rust contamination (e.g.. stale blood stains on butcher's aprons). These stains should be removed in the same way, like rust stains.
