Thanks for the info Ted.

I have access to a heavy duty parts washer that sprays turbine engine equipment up to 150*F with a chemical called citri-clean. Very potent chemical and is used on titanium aircraft engine parts, so I assume it won't hurt iron.

I knew I should be using brake clean. I have been using carb cleaner the last week and found residual gunk on the smooth iron surface.
