The development of window cleaning methods is quite interesting. It is not a complicated operation but has seen some significant improvement in tools and equipment. Originally a leather was used. Then Ettore Steccone who relocated from Italy to the USA designed a brass squeegee. He had so many enquiries from his fellow tradesmen that he started to produce copies. He approached a major hardware store and persuaded them that he had more enquiries than he could service and they ordered a job lot. The same squeegee basic design is still available today.
