The biggest advantage of using an ultrasonic cleaner for your cleaning solution is its universality. This sophisticated cleaner can reduce expensive man hours as it can effectively clean all types of materials, reaching even the smallest crevices and hard-to-reach areas.
This is made possible due to the nature of the cavitating microscopic bubbles of the ultrasonic cleaning process. When a machine or a part is submerged in the ultrasonic cleaning tank, these cavitating bubbles reach all the surface areas as long as the machine is submerged in the cleaning liquid.
Ultrasonic cleaning has proven its efficiency and ease of use, especially with smooth and contiguous materials. The cavitation bubbles implode on the contaminated area: this is the mechanical cleaning action of an ultrasonic cleaning. But if you are cleaning materials which are porous in nature, it might offer a cleaning challenge.
The overall cleaning quality of an ultrasonic cleaner on a porous material may not be the same when the same cleaning process is undergone for a contiguous material. Cleaning porous material like filters, it takes more than just loading the filter into the tank.
For a porous material like a filter, cleaning would require extra effort to remove particle contamination that is wedged into the porosity. In this case, you can load the filter in such a way where the direction of the flow is opposite to where the contamination is trapped. If you cannot identify the direction of the flow, you can rotate the filter inside the tank to get the best result.
You can also try to dip the filter multiple times in an ultrasonic cleaning tank, if it is not possible to have the cleaning liquid flow through the porous material. Just allow the absorbed cleaning liquid drain out in between dips. This assists in cleaning the porous material better.
