The notion persists that more power is better in ultrasonic cleaning applications. In the past, this may have been an absolute as the amount of power available was often limited by the limitations of the equipment that was available. As we discussed in a recent blog however, today’s ultrasonic equipment is no longer limited in power … Continued
A previous blog discussed the ramifications of contaminant loading on cleaning. This time let’s look at the long term effects on cleaning chemistry. In lab testing, the ability of chemistry to withstand extended use is often not challenged. Chemistry is prepared and used for short term cleaning trials to verify the cleaning process. In long … Continued
The risk of laboratory testing was discussed in the blog Beyond the Cleaning Lab Test Results. This blog along with others that follow will explore these implications in more detail. In developing a cleaning process in the test lab, a technician usually starts out by cleaning a small number of parts using freshly prepared and uncontaminated … Continued
The cleaning process is the “recipe” for cleaning. Like any culinary recipe, it should clearly define the ingredients, times, temperatures and the method of application to be used for cleaning. Most cleaning consists of at least the three basic steps of washing, rinsing and drying. Wash – The purpose of washing is to remove contaminants … Continued
Immersion or spray methods are used in most industrial cleaning processes. Both are effective but one may be better suited than the other in some applications and often for reasons that aren’t immediately obvious. Let’s take a minute to explore some of the benefits and limitations of each. Spray – The most often recognized … Continued
It is no secret that good cleaning followed by poor rinsing can be worse than not rinsing (or cleaning) at all. A single-use rinse using a fresh water spray or a high flow rate or single use immersion rinse are often thought to provide the ultimate rinse. These options, however, are often extremely expensive because they consume … Continued
