stevejumpr - Go for it.
Earlier this year I bought some original fenton headers.
Took about 5 hours each to get all the rust of.
A nylon brush helps while rinsing.
I used a simple 3 amp charger.
You can find Washing Soda (Arm&Hammer) in the laundry detergent aisle in grocery stores.
I have de-rusted many more items and am amazed every time with the results, compared to minimal the effort involved...
