How does dry cleaning work if it is dry?

Despite the name, dry cleaning isn’t completely dry - it simply means that no water is used in the cleaning process. Instead, garments are cleaned using a liquid solvent, most commonly perchloroethylene (or “perc”) or an eco-friendly alternative. These solvents effectively dissolve oils, grease and stains that water can’t remove, making dry cleaning ideal for delicate fabrics like silk, wool and velvet.

Here’s how it works: clothes are placed in a large machine that looks similar to a washing machine. The solvent circulates through the drum, loosening dirt and lifting stains without shrinking, stretching, or damaging the fabric. After cleaning, the solvent is extracted, filtered, and reused. The garments are then dried using warm air, pressed, and finished to look as good as new.

Dry cleaning is especially beneficial for suits, dresses, and other high-value clothing that require special care. Professional dry cleaners ensure each item retains its shape, colour and texture.
