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 […]

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 […]

Bubble, Bubble – Less Toil and Trouble

Action or Force are essential for effective critical and precision parts cleaning. As we explained in a recent Clean Source, while spray cleaning can be effective, it is line-of-sight. Ultrasonic cleaning and cyclic cavitation (also referred to as vacuum cycle nucleation or cyclic nucleation) are omni-directional. While both involve “bubbles,” […]

Spray Cleaning

On a sunny Sunday afternoon, the helpful people from Roto-Rooter visited the kitchen of the Cleaning Lady and the Rocket Scientist. They used aqueous spray cleaning to unclog our kitchen drains. Their actions were inspirational. Spray cleaning is widely used in industrial, precision, and critical cleaning. Spray can be used […]

Disruption and Cleaning Action

Cleaning is inherently disruptive. Time, Action, Chemistry, and Temperature (TACT) combine to form the disruption to achieve optimum product cleaning. It’s easy to get stuck on a single aspect of TACT, like the chemistry. The cleaning agent alone won’t get the job done. In this article, we focus on options […]

Halogenated Solvent Exposure – How low will it go?

Throughout the United States, many manufacturers may need to change the cleaning agents and/or cleaning equipment used for critical product cleaning. One reason is that the allowable worker exposure to key chlorinated and brominated solvents may become far lower. The reduced levels will come not from OSHA but rather as […]
