How are clothes dry-cleaned?
It is a process used by launderers to remove dirt and stains from clothes using little or no water. The method involves the use of liquid solvents. First the clothes are sorted and put into a large machine which resembles the domestic washing machine. It has a rotating drum that is filled with solvents to which is added a detergent. Once the cleaning is done, the solvents are drained out by the rapid spinning of the drum. Then a machine called a tumbler blows warm air through the clothes to dry them up. Later, the clothes are checked to see if stains have been removed. A device called a steam gun is used to spray water on any stain found. Certain chemicals are applied on the wet spot to remove the stain thoroughly.
