“Perfect” Cleaning Process? New Guidance

High-value product has to be clean to function reliably; but nearly all manufacturing processes inevitably generate soils. You should know about an important new guidance document. While it is designed for medical device manufacturing, it should be of value to anyone concerned with cleaning and contamination control. “Tell me the […]

“Native Advertising” Part 2 – Regulatory Agendas and More

Think critically; clean critically. To grow your manufacturing business, you must make well-informed, cost-effective decisions about critical product cleaning. Consider the source. Advertising influences our critical cleaning decisions – it’s unavoidable. In our March 2016 issue of Clean Source, we described the pervasive influence of native advertising. We showed you […]

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 […]

Location, Location, Location – Electronics Assembly

Location means everything when you’re buying or selling a house. Location is also important in critical cleaning, especially with line-of-sight cleaning. 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 […]
