Wet washing is using water as solvent for cleaning. Used together with biodegradable solutions and conditioners, water is still the most effective in removing odour and foreign particle set in fabric and textile. It is a non-toxic, environmentally safe process to clean delicate garments, utilising computer-controlled equipment and specialised equipment for the many different fabric and fiber types. Water is a good solvent and is often referred to as the universal solvent. As the water molecule is smaller than Perc it can penetrate better into fabric dissolving hydrophilic particles.

How does Wet Washing work ?
Wet washing does not use organic solvents, but rather a small amount of water mixed with detergents specially formulated for this process. Unlike household washing machines, vigorous sloshing of clothing is avoided. This allows delicate garments to be cleaned using this method. Shrinkage during the cleaning process is prevented by washing briefly at low temperatures with low velocity rotational movements. Fibre-protecting components in the detergent can prevent fibres from swelling and wool from losing its scales. Shrinkage while drying can be minimized by drying the clothing quickly under pressure at a high temperature. What you get is a whiter, softer, sanitized, fresh smelling and longer lasting linens, clothes and a cleaner environment.
