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. The brand was developed by O-Cedar, a division of Martin Marietta, in the 1950s; Drackett acquired O-Cedar from Martin Marietta in the 1960s. 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, the manufacture and use of 1,1,1-trichloroethane has been phased out throughout most of the world.
