Fine bubble technology. Cleaning applications. Test method for cleaning salt (NaCl)-stained surfaces | Status: Current, Confirmed

1 Scope This document describes the test method to evaluate the cleaning performance of ultrafine bubble water when used in high-pressure water jet to wash out salt-stained steel surfaces. The evaluation is carried out by measuring comparative removal of salt stain from the surface of a test plate with the ultrafine bubble water to that with control water.
