Any recommendations on neutralizing/cleaning the gunk of the ceramics? The green icky stuff looks like verdigris. I'd just scrub it off with a toothbrush and warm water. If that doesn't shift it, dilute acid such as vinegar or lemon juice will, but rinse the ICs thoroughly afterwards if you do that. -- Pete Peter Turnbull Network Manager University of York
