Simplifying Aqueous Cleaning Decisions
The four basic methods for performing water-based cleaning operations in metalworking are outlined and described in this article, “Choosing the Right Aqueous Cleaning Operation.”
Aqueous systems can be designed to fit almost any part cleaning application and are safer than using solvents.
Choosing the most effective aqueous cleaning method is not always easy, especially when a shop considers all the factors involved. According to the article, “Choosing the Right Aqueous Cleaning Operation,” in addition to the customer’s own requirements, manufacturers must also factor in part geometry, the material used, the shape of the chips to be cleaned, throughput, and the need for quick change-outs between different types of parts, to name some considerations.
In this article, Jeff Mills, national sales manager for the Ransohoff division of Cleaning Technologies Group, describes the four basic methods for performing water-based cleaning operations in metalworking: standard spray, total immersion, ultrasonics, and high-pressure spray. It covers how each process is performed, to which parts each process is most suited and the kind of work a machine shop is doing that would lead them to choose one process over another.

For precision parts that need to have some type of finish applied to them, inadequate cleaning and pretreatment is the biggest cause of defective painting or plating.
Cleaning is loosely defined as the process of removing unwanted contaminants or dirt from a surface. It does not alter the surface physically or chemically. A properly cleaned surface is just the same as it was prior to cleaning, except it is missing the dirt.
The development of environmentally safe, yet effective solvents has kept vapor degreasing at the forefront of cleaning operations for metalworking.
