Just putting this up as a recommendation and as an FYI for anyone looking to get parts cleaned up. Had a few bits done by Michael at vapourblast.ie

Vapour blasting is done at very low pressure and doesn't cause damage to the metal surface like other media blasting can do. Results speak for themselves.

Price was very reasonable and a quick turnaround too. Just to be clear - these haven't been painted.
