Noted, thank you for elaborating. I’ll steer clear of it on this transformer. I may only need a wire wheel, but I could probably scrub on it some with a pretty dry paste of baking soda and a tooth brush if I need to do a bit of fine tuning.

My favorite rust treatment is 6% vinegar, but that requires a long soak as well. Obviously that’s off the table for this application.
