Welcome Back!

After three + months of sheltering in place, things are slowly returning to the “new normal” here in New York state which is where I write this blog.  We all know all too well what’s been going on around the world over the past several months so I’m not going to belabor those details here.  …

Cost – First, there is the obvious cost of using more chemistry.  Most aqueous cleaning chemistries range in price from $15 to $40 per gallon but may exceed …

The Purpose of This Blog

As most of you may know (it is no secret), I am a former employee …

The Benefit of Ultrasonic Cavitation and Implosion in Cleaning to Remove Particles

An earlier blog discussed the mechanics of ultrasonic removal of soluble contaminants.  In many cases, however, it is not the soluble contaminants but, rather, particles that are the primary target of ultrasonic cleaning.  Particles of concern range from a fraction of a micron to several hundreds of microns in size.  Something larger than a BB …
