Typically around 24 hours. When I took them out, the chrome was scrubbed with a toothbrush, rinsed thoroughly with water and dried with a towel, though the hard to reach places were left to air dry. Probably would've been ok if I'd thoroughly dried all parts with a hair dryer, but I think I'll be sticking to Dawn baths from now on. I'll probably use vinegar for parts that are entirely chrome plated, as it does seem to work great on those.
