Endust is a dusting aid produced by Nakoma Products. A dusting aid is sprayed on a dustcloth or dustmop, rather than directly on the furniture. Originally, Endust consisted of odorless mineral spirits and 1,1,1-trichloroethane with a propellant blend of butane and isopropane. The Montreal Protocol targeted 1,1,1-trichloroethane as one of those compounds responsible for ozone depletion and banned its use beginning in 1996. Since then, its manufacture and use has been phased out throughout most of the world. Roger Blackwell Ph. D., of the Fisher College of Business says that Harry Drackett invented Endust. In the 1970s, however, the Drackett company offered a one-page company history indicating that they purchased the Endust product from a small company in Chicago. The Federal Trade Commission allowed S. C. Johnson & Son to purchase Drackett in 1992, provided that they divested themselves of certain Drackett product lines within one year.
