 I would only disagree with this part. I soaked rock in acid many years ago, and after 12 hours, removed all my clean rock. I then added a large box of baking soda and ended up with something resembling my kid's volcano science project 
 
For the cost of baking soda vs the impact to dumping acid into the sewer system, I'd do this as a required "just in case" step.
