What 'd be the optimum or best voltage value used in a corrosion removal electrolysis?

It is not about the voltage. It is the current that matters.
The current will depend on surface area, plate separation, and electrical conductivity of the electrolyte.

 

But.. keep the voltage low so nobody gets shocked. When I worked as an anodized I had to continuously adjust the voltage to keep the current in range, so if you can use an adjustable power supply and a current meter you are all set.

The higher the current the faster the corrosion is removed. How much current to use? Just keep things from getting very hot.
