electrolyte] 'de-ruster'? The last thing I want is to create a toxic gas or toxic 'goop'. I realize this is sort of an anti-plating question, but I have read more than numerous websites regarding this type of rust removal, and none have broached the subject. Also, I figured I would get the most accurate answer from here. Thank you, Owen

You're not going to create any toxic gas or goop, Owen. But aluminum is attacked by strong caustic, so I would expect some pitting. Further, I'd be surprised if the idea worked anyway unless your experience indicates that it will.
