REMOVAL OF STAINS WITH SOLVENTS AND STAIN REMOVING PASTES

In most cases, the use of an appropriate solvent dissolves the substance, which caused the stain, then its absorption by a pad of high water absorption. In this stain removal method, the tampon of the multi-folded rag is moistened with a solvent, then the solvent is rubbed in harder or lighter (depending on the type of fabric and contamination) into the fabric, moving the tampon over it in circular movements. However, do not move the tampon back and forth, because in this way the dirt from the stain is spread to the clean places of the fabric (drawing).

Correct stain removal with a solvent or ordinary stain remover. A cloth is placed under the stained area and a stain remover is rubbed in with a tampon, making circular movements

The described activity is repeated several times until the moment, when the stained area becomes completely clean. At the end, the stain is additionally wiped with a clean one, dry tampon, thus evenly distributing the excess solvent, and finally the place of the stain is wiped dry, to finally remove residual solvent. If, after these treatments, there are still visible traces of stain, wipe the stained area with a clean rag, lightly sprinkled with gasoline. It is extremely important to follow, so that the dissolved staining substance is absorbed completely into the rag, otherwise, the dissolved dirt will contaminate the clean areas of the fabric around the stain, which will enlarge the stained area.

For stain removal it is recommended - as already mentioned - linen or terry cloth rags with high water absorption or - in the simplest cases - lignin. However, when using lignin, it is impossible to avoid fraying and settling of its fibers on the surface of the fabric, Therefore, in this case, a careful brushing of garments after removing stains is essential.

Fabrics, knitted fabrics and pull-overs are made - as is known - from fibers. Therefore, strong friction is unacceptable, especially for delicate fabrics (velvet, natural silk, dederon, rayon or rayon rayon), and also for loosely woven fabrics, like for example. tweed or homespun. Due to strong mechanical action, the fibers are shifted and "bald spots" or simply holes are formed. For tight fabrics (e.g.. welwet) damage to delicate fleece or abrasion of the fibers may result, creating visible damage on the surface of the fabric.

Greasy stains, after wetting them with a solvent, spread - as you know - very quickly, which causes the surface of the stain to increase. To prevent the dissolved fat from soaking into the fabric, moisten the area around the stain with water, thus avoiding the formation of the so-called. areola.

Lightly soiled areas can be easily cleaned with a tampon soaked in a solvent, however, even then the fabric in the area of ​​the stain may get dirty. In this case, wipe the area around the stain several times with a clean tampon, each time immersed in fresh solvent.

One of the most recommended stain removers is gasoline, especially, that - as mentioned - it does not damage both natural fibers, and synthetic. The disadvantage of gasoline, however, is its flammability and quick evaporation, which in turn causes, gasoline vapors mixed with air can explode. Therefore, when removing stains with gasoline, carefully extinguish all possible sources of fire, like for example. gas flame, cigarette etc.. Gasoline vapors spread extremely quickly, they get into adjacent rooms through an open door and it can happen, that they will light up, for example,. from the gas flame in the bathroom, from a spark in an electrical device, etc.. If you are not careful, it may have dangerous consequences, strong outburst.
