Long tomorrow, been sick.
Washed the board again, this time for 1 hour 40 minutes in solution of around 2 parts water to 1 part lemon juice and the board looks quite a bit cleaner, it's drying now in Frankenoven so I will inspect it later tonight and write back. I am also going to get some small pieces of metal and some screws to make the action of the bath a little less relaxing.
I will up the temperature of Frankenoven from 40 to 50 degrees, the boards are taking way too long to dry and an extra 10 degrees will not harm the board.
First inspection of the board shows the lemon juice interacts with flux residue to form a slightly powdery substance, a stiff brush will fix that issue, other than that the board looks very clean.
