Hi Jim - I have always thought about a ph balancing wash to neutralize the acid, and am sure it is a good idea to do so. It certainly makes perfect sense. However, I have used the water rinse-only method for about 15 years now, with no ill effects. It is highly water soluble, I guess. At any rate, I think the advice the chemist gave you is good; perhaps unnecessary, though.
