Precision cleaning is just part of the process.  To assure compliance, Cleanliness Testing for Solid Particles, Non Volatile Residues, Chemical and metal contamination can be performed by one of our outside labs.


Chem Cleaning of materials is vital part of many high tech operations such as disk drive, semiconductor, aerospace and medical industries. Since a strong scientific base has been the corner stone of all high tech industries which require cleaning as a necessary process step, therefore, it is highly advantageous for the cleaning industry to stand on an equivalent scientific platform and very critical to have access to all relevant scientific information. Through this knowledge base the intelligent decisions on the etch time and etch chemistry can be made.

The purpose of any cleaning process is to remove contaminants from a part that needs to be rendered clean. Contaminant removal, through chemical means, involves a chemical reaction that modifies the chemical composition of contaminants. Contaminant depositions could be in multi-layers which may be impossible to obtain a chemical solution to remove all contaminants in one step process. Moreover, it is very important to understand the dynamics and factors that influence chemical cleaning.  Cleaning contaminated parts involves two key steps; mass transfer and reaction kinetics, which consist of many dimensionless numbers. An increase in the value of dimensionless numbers such as Reynolds number, bulk Peclet number, Sherwood number and Schmidt number leads to increase in contaminant removal rates and hence the cleaning process.


Clean Sciences, Inc., offers stainless steel passivation, nitric passivation & citric acid passivation.

  • ASTM A 967, Chemical Passivation Treatments for Stainless Steel Parts
  • ASTM A 380, Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment and Systems
  • Federal Specification QQ-P-35C, Passivation Treatments for Corrosion Resistant Steels


Ultrasonic Cleaning is achieved by using transducers in or attached to the bottom of a tank to emit and radiate sound waves through the cleaning solution.  These sound waves cause millions of microscopic bubbles to form and grow, this process is called “CAVITATION”. These Ultrasonic Cleaning bubbles then collapse or “implode” releasing enormous amounts of energy. These implosions work in all directions to Ultrasonically Clean and remove contamination from the work piece. Clean Sciences, Inc., offers Ultrasonic Cleaning utilizing high purity solvents and detergents. All process solutions are monitored and controlled to ensure consistency and repeatability.
