New user here, just starting out in the amazing world of machining.
Background
-We create proof-of-concept prototype hardware and have a small, but very capable shop that we keep meticulous not only for good housekeeping practices, but because of risk of cross-contamination.
-We never had any issues with rust of any kind.
Challenge
Recently, we had to create sleeve bearings using C932 Bearing Bronze and used the lathe, mill, drill, and bandsaw in their creation.
Almost instantly, we noticed rust where we handled previously non-rusting surfaces (see attachments)
Nothing seems to remove it- we have tried Acetone, Alcohol, WD40, Silicon, lubricating oil, to no effect. The Silicon spray works temporarily, but ultimately the rust comes back.
I do not know where to go, have researched on the "interwebs" for hours, and have found nothing to help.
Any/all assistance or guidance would be much appreciated.
Thank you!
