Cleaning brake booster for paint prep

[eagleguy]

I just got a Cardone refurbished brake booster to make my vacuum brake swap. The unit was bead blasted and ready for paint but appears to have a light coat of oil on it. What is the best way to clean it prior to painting. I was just going to wipe it down with brake cleaner. Will that be sufficient or do I need to wash it with Dove or some other soapy cleaner which I think could cause me rust issues I do not have at the moment.

Use an auto body pre cleaner or quick drying solvent like lacquer thinner, acetone, etc. Don't use water on bare metal.
