I share your pain. Perhaps a gentle cleaning with deoxit rubbed with a cotton swab might save the day on the tuner contacts. I wouldn't spray it, but if all you have is the spray, spray it in the cup, and then proceed. OK to pass a piece of good old paper gently between the contacts back and forth a couple of times to help this along. Let it dry out for a day before firing it up, and let us know. We'll go on to the chopstick probe next if needed.
