ESC not turning on

I have a HPI waterproof ESC, but the switch is not waterproof and I think the contacts are rusted. Last time it did not work, I soaked the switch in lemon juice and that seemed to dissolve some of the rust and got it working again. This time it doesn't seem to work at all no matter what I do, does anyone have any suggestions?

The white wire is a signal wire, it is used for setting up procedures, I would be looking for a replacement switch and placing it in a waterproof bag or similar. You could run an extra switch just on the red and black, but I am not sure what will happen when you need to use the little button (white wire) for programming
