Is there a coating/oil/etc that is commonly used for this?
We're doing some work where we'll have to machine steel parts months ahead of when they'll be welded. These will be tight tolerance parts to be used for in a precision mechanized TIG application and are planned to be stored in typical shop conditions. From experience, we have some concerns about preserving the material surface condition during this time.
I'm looking for something that's going to come completely clean with Acetone or Alcohol and not dry out or run or otherwise degrade during staging. I know oil is typically used for steel from suppliers, however I don't have enough experience with it to know if it's some super special yankee doodle dandy metal coating oil, or if it would perform how I need to, or it would come clean enough for precision mechanized TIG, or... I'm not against just using 30 wt engine oil, but I don't want to gain "experience" on these parts
