One more happy customer ...

Hi Tom,
just thought I would let you know I decided to try the CorrosionX on the two salt water damaged boards (GPS module of a drone) and the CorrosionX recovered both of them just one of the minor boards didn't respond. So I am over the moon with the results!
This is after A technician had Sonic cleaned them then looked at them through a microscope and told me there was not any hope for recovery.

Thanks again for your help Kevin Berkefeld
