Residue

Residue is the enemy of a properly-functioning product. Manufacturers demand a “perfectly clean” surface. We are experts in critical cleaning – but critical cleaning is not the same as achieving zero residue. Rather than aiming at a perfectly clean surface, aim for the right cleanliness relative to subsequent storage, assembly […]

New Substrate, New Cleaning Part 2 – Polymers, Glass, and More

Back in the mid-1960s, an iconic movie featured a recent graduate, played by Dustin Hoffman, who was attempting to find himself. One of the “old boys” came up to him and, in a solicitous voice, whispered a single word: PLASTICS. If you manufacture product, I am here to whisper: “plastics,” […]

Rosie, Robots, and Critical Product Cleaning

Everyone in manufacturing – men and women – can benefit from the experiences of “Rosie the Riveter,” an icon of the World War II era.  I was reminded of Rosie while reading a thought-provoking article on LinkedIn that reviews fifty ideas to watch this year. Some trends are disturbing in terms […]

Dust Storms, Detecting Contaminants, and Critical Cleaning

How clean is clean enough? You test for a contaminant. The results indicate contamination level is zero, but the product still fails – it’s as if the contaminant is still there. What happened? Even with a clean manufacturing facility, you can be caught in a detection dust storm, one that […]

New Substrate, New Cleaning Part 1 – Metals

Let’s change just one thing: the substrate. The product line remains the same – same size, same shape, same end-use requirements. Do you have to re-evaluate the cleaning process? Absolutely! To head off production shut downs and to avoid losing business, test the new substrate with the current cleaning process […]

Critical Cleaning, Trade Shows and The Mall

You are off to a trade show to find a great critical cleaning process. I’ve run across a few articles about what to do to make the most of a particular show. Planning and conference apps and checklists are a start; but they won’t give you the full benefits. Effective […]

What’s in your cleaning bath?

It’s a continual source of amazement, or at least amusement. A manufacturer expends considerable time, engineering effort, and expense in designing a product. The marketing folks tout the product’s advanced superiority in trade publications, conferences, and web sites. Then, the assemblers have to actually build the product. Yield problems arise. […]

EPA Lautenberg Update – A Window of Opportunity

The EPA is further scrutinizing cleaning solvents trichloroethylene (TCE), perchloroethylene (PCE, tetrachloroethylene), methylene chloride (MC), n-methyl-pyrrolidone (NMP), and n-propyl bromide (nPB, 1-bromopropane). We discussed EPA actions in the February issue of Clean Source.  Now, the EPA has published new documents relating to these solvents and five other chemicals and has […]

Participants included manufacturers in the areas of automotive, optics, medical, and metal finishing as well as developers of cleaning chemistries, cleaning equipment, and techniques for surface analysis. The workshop confirmed our expectation […]

Can you follow your own cleaning specifications?

Specific written instructions about the cleaning process don’t necessarily translate into profitable manufacturing. Consider the wisdom imparted by the classic, mid-century T.V. commercial featuring tuna with good taste (a fish exhibiting faux upper-class behavior) and then touting the superiority of tuna that tastes good.  Successful, profitable manufacturing requires both the […]
