Salad Dressing and “Layered” Cocktails

During a recent cleaning and chemistry course, a student asked a thought-provoking question about solubility, miscibility, and cocktail hour.  I explained that some liquids, like oil and water, are immiscible. That is, they don’t form a “single phase;” the oil is on top of the water. The observant student wondered […]

Think Critically, Clean Critically – “Native Advertising” Part 1

To me, “native advertising” evokes the cast of “Madmen” in vintage business suits and starched white shirts sitting cross-legged, somberly thumping on bongo drums with one hand and hoisting diet sodas with the other.

In line-of-sight cleaning, the cleaning force is directionally-aimed at the part or component. Do you use line-of-sight cleaning?  Most electronics assemblers remove flux and other residual soils using in-line […]

What Is Clean Enough?

Suppliers of cleaning chemistry or cleaning equipment may claim their product “successfully cleans” heavy greases, particles, fluxes, and other soils. Private companies, military, and governmental agencies report successful cleaning in selecting a particular cleaning agent. What does “successful cleaning” actually mean for your manufacturing process? Success is a matter of […]

Travels: The Future of Critical cleaning

Last year, our vacation was a day and an evening in Cleveland. Cleveland has much to offer – the “Rock & Roll Hall of Fame, innovative restaurants!  Truth be told, our vacations end up getting squeezed in around conferences and committee meetings.  Recently, our travels have taken us to PCx […]

Supply Chains and Critical Cleaning

If you are involved in manufacturing, if you are part of a supply chain, rugged critical cleaning processes will improve your productivity and profitability. You may be an OEM, a job shop, even a repair/rework facility. You may be the ultimate customer and have little or no direct contact with […]

Fire and Water – Acetone

I was in the middle of my program “Cleaning Catastrophes” at the Parts Cleaning Expo (PCx) in Columbus. The sea of faces in the audience brightened expectantly when I began the topic of mixing acetone with water or with aqueous cleaners.  I had to squelch everyone’s enthusiasm by explaining that […]
