It will come as no surprise to anyone who is involved with industrial parts cleaning that rinsing is an expensive but important part of the process. Although it may not reduce your wardrobe to “rags,” proper rinsing can put a sizeable dent in the cleaning budget. Let’s talk a minute about how to reduce the cost of rinsing. The …
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 …
Have a Happy and SAFE Fourth of July!
When I first started working with ultrasonic cleaning back in the early 1960’s “ultrasonic” meant 20kHz. That’s all there was! Some very early sonic cleaning equipment used by one of the major automotive manufacturers in the prior decade had operated at 10kHz using a motor/generator to develop the driving signal for some very crude transducers …
Having a means to evaluate and monitor the cleanliness of parts after cleaning is essential to assure the success and consistency of any cleaning process. Selecting and properly applying the appropriate cleanliness test for a particular application is a task that should not be taken lightly. A cleaning test should be able to quantify the …
The vast majority of industrial cleaning processes today use water-based chemistry for cleaning and the cleanest water possible for rinsing. Most water comes from wells or reservoirs and arrives via a municipal utility which may filter it and add chemicals to kill and prevent the growth of bacteria and/or provide certain health benefits. Other than …
Many cleaning specifications call for “Spot Free Drying.” I have always taken this to mean that there should be no visible water (or other) spots on the parts once they exit the cleaning process. The offending spots are usually created when water evaporates leaving behind a solid residue. The resulting residues or spots are cosmetically …
The use of some kind of chemistry is an important and unavoidable part of most industrial cleaning processes. Chemistries can remain effective for as little as a few hours or as long as a year or more depending on the chemistry and how it is used. In the end, however, cleaning chemistry must be disposed …
Somewhere along the way, maybe half a lifetime ago, I got involved in photography on a semi-professional basis. I photographed a bunch of weddings and also spent a lot of time cruising around back roads taking pictures of birds, colored leaves, snow banks, flowers and whatever else I thought was interesting that got in the …
Ultrasonic agitation of cleaning solutions is just one of many tools that can be used to facilitate and enhance a cleaning process. High frequency vibrations are introduced into a bath of liquid cleaning solution by specially designed devices called transducers which are similar in concept to loudspeakers but designed to operate at much higher sound …
