Dragon et al,
I generally do not recommend electrical spray cleaners as there are so many additives it is hard to know the effects of each. Many contain solvents that are harmful to plastics or contain any of a variety of lubricants. Some may contain trace amounts of chemicals that can conduct at high frequency which will wreak havoc with micro procs and controllers while seeming to be benign for low frequency signals.
