Zep
Zep was founded in 1937 by three entrepreneurs, Mandel Zhaban, William Eplan and Saul Powell, with a vision to create value for customers by offering a comprehensive range of high-quality industrial and janitorial cleaning products backed by unique chemistry, exceptional service and unmatched technical support. Zep was acquired by National Linen Services and subsequently became a subsidiary of National Services Industries ("NSI"), a diversified industrial and services group.
