Well, it's not very refined really, I just dunked the circuit and the corroding metal parts in the type of vinegar you use for cleaning, and after a while dunked the whole mess in petrol, (white spirit?) to wash away the vinegar. It was broken anyway, so I thought I couldn't make it worse anyway. More forum members have used the vinegar method, just search the forum :)
