Answer
What is it that you want to clean now?  I'm not exactly sure what it is that you need.  Ummm.. but, iF I had to take a wild guess about your problem, your fuel guage sender is probably dead or the wires to it are corroded.  You can check if the sender is dead by getting a voltometer.  The sender is on the fuel pump, which is under the backseat of your car.
