kuivapesutekniikkaa

Kuivapesutekniikkaa, often referred to as dry cleaning in English, is a method of cleaning fabrics that uses chemical solvents instead of water. This technique is particularly useful for delicate garments that could be damaged by traditional washing methods, such as silk, wool, and rayon. The primary goal of kuivapesutekniikkaa is to remove stains and soil without shrinking, stretching, or fading the fabric.

The process typically involves placing the garments into a specialized machine where they are tumbled in a solvent, such as perchloroethylene (perc), petroleum solvents, or newer, more environmentally friendly alternatives like silicone-based solvents. The solvent dissolves oils and grease, while a detergent is often added to help lift water-soluble stains. After the cleaning cycle, the solvent is filtered and recovered for reuse, and the garments are then dried, often in the same machine or a separate drying unit, to remove any residual solvent. Finally, the clothes are pressed or steamed to restore their shape and finish.

Kuivapesutekniikkaa is effective for a wide range of stains, including oil-based stains like lipstick, ink, and grease. However, it is less effective on water-based stains such as sweat, blood, and most food stains. For these, pre-treatment or a combination of water and solvent cleaning might be necessary. While often referred to as "dry cleaning," the process does involve liquid solvents, but the key difference from traditional laundry is the absence of water in the main cleaning stage. This method helps preserve the integrity and appearance of many textiles.
