If I do the Oxalic acid flush and then rinse and add straight water to the system but don't have time to do the 2nd Oxalic acid flush for a few days, do I still need to do the baking soda neutralizer addition? Or can I wait to do the neutralizer until I am finished all of the oxalic acid flushes?
(Assuming that I rinse each time after oxalic acid flush with water and fill the system with water).

This means that there might be some small residual Oxalic acid in the system for a few days. Is this ok? Or can it start to eat away at something
