Water soak followed by a baking soda soak & rinse.
I'd let the soak go for an hour or so.
The soda will help ensure that you've got all the acid out.
Sometimes things can crystallize and be tough dissolve and move.
This is a problem when people store things in the same cabinet which ought not be stored together such as Nitric acid and Toluene. Crystals of the dried solutions can form in the threads and can also be contaminated by the other chemicals in the locker and when you twist them off can detonate.
A little tiny ignition in a toluene bottle can be a very embarrassing moment.
