If the parts are small enough, I submerge them in a drum of caustic soda and connect the battery charger to it and an electrode also hanging in the caustic. I vary the current by increasing/decreasing the amount of electrode in the caustic so I use all the charger can put out without going off the scale. Sometimes, it is just a piece of sheetmetal offcut, sometimes a piece of rod so it works for the whole length of the component.
Parts come out with out paint.
