Cleaning with Organic Solvents, Part 1: Names and Structure

Manufacturers are exploring moving to new critical product cleaning processes that use either organic solvents or water blended with a bunch of chemicals, including organic chemicals. We’re going to get to know a little about molecules. Why bother? Perhaps you are reading product literature that asserts superlative cleaning performance of […]

Interesting Times for Manufacturers

“May you live in interesting times” is a thinly-veiled curse, one that no doubt resonates with manufacturers involved in critical product cleaning. In the United States, current interesting times arise from a confluence of multiple factors. One set of factors is the regulatory activities at the Federal and State level […]

Critical Cleaning, Wettability and Solvency

To clean effectively, the cleaning agent must access the surfaces of the product. In contrast with flat surfaces, it is very difficult to reach all the surfaces of complex, ornate, or miniature products. Electronics assemblies with spacing below 0.005” (125µ) are not as readily cleaned. The more surface area, the […]

The Value of Direct Interaction

The Cleaning Lady and the Rocket Scientist were LIVE and in person at the recent Parts Cleaning Conference in Chicago. The refrain of the new normal goes something like: “Yippee! We’re talking to each other face-to-face, in person.” Was the conference useful?  In our opinion, yes. The Parts Cleaning Conference […]

The Power of Hydrogen: pH and Aqueous Cleaning Agents

We all know that “oil and water don’t mix,” that like dissolves like. We’ve heard statements that solvents (organic solvents) work for non-polar soils while water works for salts. Critical product cleaning, like life, is complex; and the range of soils even for a given manufacturing situation are more varied. […]

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 […]

Degreasing and Fireworks

In line with Independence Day fireworks, here’s breaking news! The U.S. EPA is taking steps that will likely severely restrict use of chlorinated and brominated solvents used by manufacturers in critical cleaning and degreasing. On June 30, the EPA announced that they are revising their risk assessment for perchloroethylene (PCE). […]

Higher Profits with Less Water

The Cleaning Lady and the Rocket Scientists are in California where there is a water shortage, so the water from cleaning veggies goes directly on our tomato plants. Water is a limited, valuable resource. In manufacturing, using water strategically in critical cleaning can cut the costs of the cleaning process […]
