A self-service laundry is a facility where clothes are washed and dried. They are known in the United Kingdom as launderettes or laundrettes, and in the United States, Canada, and Australia as laundromats (from the genericized trademark of the Westinghouse Electric Corporation)[1] or washaterias. George Edward Pendray created the word "laundromat" for Westinghouse.[1]
Laundry
Various chemicals may be used to increase the solvent power of water, such as the compounds in soaproot or yucca-root used by Native American tribes, or the ash lye once widely used for soaking laundry in Europe. Soap, a compound made from lye and fat, is an ancient and common laundry aid. Modern washing machines typically use powdered or liquid laundry detergent in place of more traditional soap.
When no watercourses were available, laundry was done in water-tight vats or vessels. Sometimes large metal cauldrons were filled with fresh water and heated over a fire; boiling water was even more effective than cold in removing dirt. Wooden or stone scrubbing surfaces set up near a water supply or portable washboards, including factory-made corrugated metal ones, gradually replaced rocks as a surface for loosening soil.
Once clean, the clothes were wrung out — twisted to remove most of the water. Then they were hung up on poles or clotheslines to air dry, or sometimes just spread out on clean grass.
