Use dedicated brushes for each bin. A lint-free cloth should come back clean, and the cleaner solution and rinse water should both produce no fluorescence under UV (black light). Dry passively, or with filtered air or bottled nitrogen so as not to reintroduce any contaminants. Any subsequent lubrication or assembly with lubricated soft parts should be done with oxygen compatible lubricants (i.e. Christolube).<br><br>Sean<br><br>Sent from ProtonMail mobile<br><br><br><br>-------- Original Message --------<br>On Jan 6, 2018, 09:23, Steve McQueen via Personal_Submersibles < <a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:</div><blockquote><br><div><p>All, I am working on cleaning some parts/pieces for O2 service on my K-250.
