Hey guys,

I decided to do a full cleaning of my realforce 91u keyboard so I took everything apart and i washed the metal backplate with the switches on it with distilled water. Overall the cleaning was a complete success, the keyboard looks and feels brand new. But the space bar is creaking when i press it (i tend to press it off-center to the left with my left thumb: From what i understand all i need to do is pull the keyboard apart again (all 30 screws, yay!) and apply some lube on the switch. So my questions are:
- what kind of lube and where can i order it from in Europe/Austria
- i have some silicon grease, would that do?
- is there anything i can do *without* opening the keyboard right up again? like lube the switch from the top side?
- should i just replace that one switch with a different switch from a less-used key?

Thanks
