Cleaning Verification in Complex Geometrical Surfaces

Technical cleanliness of small parts and components refers to the absence of contaminants, ensuring optimal performance. It is vital to prevent potential issues such as wear, malfunctions, or failures caused by the presence of particles or foreign substances. Maintaining technical cleanliness is crucial for guaranteeing the reliability and longevity of the parts and components in various industries.

The current state of the art

Cleaning effectiveness for small components or parts can be assessed through various methods such as visual inspection, swab testing, gravimetric analysis, or particle counting. In the case of complex geometrical surfaces and intricate parts, cleaning verification is often accomplished using visual inspection or Riboflavin testing. The objective is to visually confirm that all surfaces have been in contact with the cleaning solution, ensuring thorough cleanliness.

Limitation & Challenges 

Incomplete Surface Coverage

Being in solution form, may not effectively reach or adhere to all surfaces, especially intricate or hard-to-reach areas.

Limited Detectability

Hard to detect contaminants that are not easily visible or may be present in small quantities.
