This is our eleventh column about technical aspects of cleaning. Doesn't time fly when…This month I want to change direction a bit. The first ten columns have covered the basic fundamentals of solvent and aqueous cleaning technology, how to purchase a system, what its costs should be, new products found in the marketplace, and new technology to come.Now, I am going to shift emphasis to applications, solving of practical problems, and avoiding problems. This may sound like a switch to a "Q A" column, but I intend it not to be that. I intend this change to be a natural, cyclical on--from theory to practice. In "X" months we'll return to the fundamentals. I see my mission with this column as educational and I am just shifting from one type of information to another.I'll write from my experience and that of my clients (unidentified). I'll write from my perspective--an unbiased industry consultant. I'll avoid questions better addressed to suppliers ("at what pH should my XX cleaning system be maintained if the temperature is YYdegF?). You will be able to read and learn in this column about situations where cleaning technology is employed.Readers of previous columns have told me they don't like the "Q A" approach because it is too application specific. I think they mean that their specific problem wasn't covered in that column or that the lag time between submission of a question by E-mail and reading an answer was longer than their boss allowed for solution of the problem.
