Presently, industry places heavy reliance on the use of chlorinated solvents to achieve acceptable levels of cleanliness for systems in oxygen service. The Montreal Protocol and other restrictions will prohibit the use of these types of solvents because of potential damage to the environment. This paper discusses some of the issues involved in assessing aqueous based cleaning agents. A gravimetric test procedure has been developed to have a standard method of comparing the ability of a cleaning agent to remove oil and grease contaminants from prepared metal coupons. Data is presented to demonstrate the results of the test procedure. The testing addresses the use of a soak method and ultrasonics. The effects of time and temperature are directly addressed. Other variables are discussed in general terms such as disposal and cost considerations.

With all the cleaning approaches available, how do you choose which one is best for your needs? Components manufacturers wonder which will provide a competitive edge. Chemists and engineers worry about the effect of any process modification on a critical component or on the stability of an irreplaceable antique. There is no silver bullet, n

The focus of Handbook for Cleaning/Decontamination of Surfaces lies on cleaning and decontamination of surfaces and solid matter, hard as well as soft. Bringing together in a 2-volume reference source: - current knowledge of the physico-chemical fundamentals underlying the cleaning process; - the different needs for cleaning and how these needs are met by various types of cleaning processes and cleaning agents, including novel approaches; - how to test that cleaning has taken place and to what extent; - the effects of cleaning on the environment; - future trends in cleaning and decontamination, for example the idea of changing surfaces, to hinder the absorbance of dirt and thus make cleaning easier. A brief introduction is given to the legal demands concerning the environment and a historical background, in terms of development of detergents, from soaps to the modern sophisticated formulations. Bactericides, their use and the environmental demands on them are covered. Thorough discussions of mechanisms for cleaning are given in several chapters, both general basic concepts and special cases like particle cleaning and cleaning using microemulsion concepts. * General understanding of how cleaning works, function of ingredients and formulations * Overview of environmental issues and demands from the society in the area * Gives basic formulas for cleaning preparations in most areas

A solvent composition for displacing greasy and oily contaminants as well as water and/or aqueous residue from metallic surfaces, especially surfaces of radioactive materials so that such surfaces can be wiped clean of the displaced contaminants, water and/or aqueous residue. The solvent composition consists essentially of a blend of nonpolar aliphatic hydrocarbon solvent having a minimum flash point of about 140.degree. F. and 2 to 25 volume percent of a polar solvent having a flash point sufficiently high so as to provide the solvent composition with a minimum flash point of at least 140.degree. F. The solvent composition is nonhazardous so that when it is used to clean the surfaces of radioactive materials the waste in the form of paper or cloth wipes, lab coats and the like used in the cleaning operation is not considered to be mixed waste composed of a hazardous solvent and a radioactive material.
