Precision cleaning in micro parts can be crucial for many reasons.

It may be to ensure an aesthetically perfect; spot-free clean of jewellery or watch parts, or to ensure miniature high-speed bearings in dental instruments are hygienic before use. A speciality fluid, compatible for use with most metals, plastics and rubber, is needed to meet these requirements.

Fluorochemical surface modifier coatings can be used as a non-wetting barrier coating to prevent lubricants from migrating from critical wear zones in micro-mechanical mechanisms such as watch parts and gyros used for navigation.  A thin coating applied to the outer race of a miniature bearing can proven lubrication loss.
