Anyone that dipped any bolts for an extended period notice the the threads getting eaten away ? I haven't used this particular mix, just white vinegar itself, on a set of lower control arms and left them in for over a week, the threads on the exposed part of the t bar adjustments were eaten to the point of the bolts being junk.
How bad were they to begin with? If the corrosion is really deep all you're removing is the oxidized metal and the damage was done well before it was put in the bath.
With different materials and levels of corrosion, it's best to check at least a once a day on the progress.
I know the galvanized headlight buckets tend to lose their "sheen" within a few hours and don't require near the time to de-rust and clean while I had shock plates in the solution for 2+ weeks.
