Yes, I agree. You can use glass cleaner for the LCDs too. Don't let the solution go down into the crevice where the frame is. Light spray and wipe with a rag.
Spray the rag then wipe. Spraying in to any device is asking for trouble.
The best thing I have found is the little prepackaged moist towels that come with fast food to wipe your hands with. They clean any thing rather well. And smell good to boot...
