Blackstone Ultrasonics was founded in the mid 1950’s in the hope that the addition of ultrasonic agitation to a conventional clothes washer would revolutionize laundering of fabrics. It didn’t take long before it was recognized that ultrasonic techniques weren’t going to be effective – at least not by simply adding ultrasonic transducers to a conventional …
Gee Whiz! I was sure somebody would challenge me on the last blog about washing dishes at home. But, since there are no comments (or fire bombs) in my inbox, I guess everybody agrees that the most efficient way to wash dishes at home is the “old fashioned” way with a dish rag and dish drainer. …
Water, the “universal” solvent is the center of most cleaning applications in the home. Water, at least in my location in the US, is readily available, plentiful and relatively inexpensive. Water plus a small amount of overly expensive and competitively merchandised chemicals does an admirable job of cleaning dishes and clothes which constitute about 50% of …
“Vanishing Oils” are often considered as an alternative to more conventional lubricants in light duty stamping and forming operations. The conception is that these formulations actually “vanish” eliminating the need for cleaning once there is no longer a need for lubrication. True, depending on circumstances, they may reduce or eliminate the need for cleaning but in fact, …
Inadequate or improper agitation of parts in a cleaning tank is a common problem in industrial cleaning. Agitation, if properly applied, can be a very powerful aid to cleaning. The result of improperly applied agitation, however, can range from disappointing to disaster. The basic reason to agitate a part in a cleaning tank is to provide or …
The blog It’s Time To Talk About Water discussed the variations in water from different sources. Today’s blog is the start of a series on how to purify and prepare water for use in cleaning and rinsing applications. Water from municipal and other sources may have characteristics that are deleterious to a variety of processes. Many of …
Previous blogs discussed the demise of solvents after the Montreal Protocol. Today, in the US at least, solvents are coming back prompting the reader to ask, “What Has Changed.” First of all, there was never any real argument that solvents did, and still do, a good job of cleaning in many, many applications! Are there aqueous and other alternatives …
Having a definition of a “clean” part and a means to quickly and effectively determine if the the criteria for cleanliness has been met is very critical to the success of any cleaning process. The problem, however, is that there are so many ways to define and detect cleanliness that the task can be a …
There are four basic variables that, combined, establish the success or failure of any industrial cleaning process. The variables are Time, Temperature, Chemistry and Agitation. Although there may be additional variables – things like fixture design and variations in the process prior to cleaning – which can have major impact and, in fact, make or …
Today’s industrial parts cleaning processes commonly employ at least three distinct steps. The basic steps are Washing, Rinsing, and Drying. Each step is custom tailored to the overall requirement with the range of options for each much broader than one not intimately involved with the technology might imagine. In some processes, in fact, it is …
