Process Flow

29 people coming to dinner? No problem! I thought it was all under control. The apple and pumpkin pies were cooling nicely. The turkeys were out of the oven. The ovens were pretty much empty (or at least, I didn’t see billows of smoke). I placidly sipped red wine as […]

The Physics of Cleaning, Part 8: Builders

Oil and water do not mix (at least not readily); so how can manufacturers successfully remove oil from product using water? The key is in the formulation, in the secret blend of “herbs and spices;” or, for fully-formulated aqueous cleaning agents, in the blend of chemical additives, most of which […]

Too Much of a Good Thing

“All things are poison, and nothing is without poison; only the dose permits something not to be poisonous.” This 16th Century statement by Paracelsus states that at some level there can be too much, even of a good thing. Here are 8 examples where “more” is not better for critical […]

Compatibility  – You Can’t Rely on Eye Charts

“The surgery was a success but the patient died.”  As a manufacturer, you are the surgeon. Think of the product as your “patient.” The goal of cleaning is to remove soil, or matter out of place.  If as a result of the washing, rinsing, and/or drying step the product is […]
