I have an iMac G5 keyboard with key action that is not as smooth as it should be. I've cleaned it, thoroughly, but some keys still feel a bit tight. I don't think it was ever the best keybiard in the world...
It's the type in which each key spring is a little cup of what I think is silicone rubber.
I want to lubricate the keys. What would be the best kind of lubricant - a dry power, or a silicone grease spray?
Silicone grease from a tube in the past wasn't very effective - it collected a lot of dust which made the keyboard stickier.
Maplin offers:
Silicone grease with PTFE:
Multipurpose silicone grease:
I can't find a dry power spray I used to use though.
Thanks for any suggestions.
