Hence any reasonable method is Ok.
If you are using oxalic acid it must be neutralised, as with any of the mineral acids that you might be using in the removal of interfering minerals.
One simple way is to have some forms of Calcium Carbonate on hand.
eg Calcite, limestone, marble, etc.
When you need to remove the acid you just put into the bath of, now weakened acid, any of the listed materials and wait until there is no sign of any gas being released.
When you reach this stage, the acid is neutralised and can be disposed of.
I must add in order to make sure this reaction is completely over, there must be excess Calcium Carbonate, left on the bottom of the container..
