How do I clean a circuit?
I have a gas stove with an electronic control pad that has been stored for more than three years. We moved into a house where we can have our stove again, and everything works except for two buttons. I took the circuit board to inspect, and it is covered with bug remains and crud! I'm sure if I can get the crud off the circuit board, the buttons works again. But I do not want to damage the card in the process. Suggestions? I went to Radio Shack and bought a box of their own contact … NOT CHEAP! At nearly $ 12 for a small box (10 oz), I hope it works! If not, I'll go with alcohol Friction instead (this volume is much cheaper!) I'll let you know before I choose the best answer.
In any electronics store you can find a Contact Cleaner spray. It is inexpensive and leaves no residue in the circuit. The liquid evaporates almost instantly, and can be put into service as soon as you get together.
