The Contact Cleaner is just an inert gas -- like tetrafluoroethane (the hydrocarbon acts as both the propellant and the active ingredient). Useful for cleaning the dust out of confined spaces, but it's more like blowing air than anything else. It won't clean the fingerprints off anything. The chemist's alcohol wipes are fine for what you used them for, they were probably a 70/30 mix of isopropanol and water like you would find in a first-aid kit, which basically the 75/25 combination I referred to in my previous e-mail. But if they contain ethanol, they wouldn't be suitable for plastics.
