Yeah. I seemed to have found a way.. mistakingly!
A couple weeks ago I spilled some juice on my keyboard, thankfully nothing was damaged but i ended up with like 10 keys on my keyboard extremely sticky, and everyday it would just get worse... and it was just that more frustrating.
I had used baby oil to moisten my skin randomly after a friend told me it was good.. My hands were still oiley and I was just responding to facebook chat, didn't even know I had mistakenly greased up my keypad..
A couple hours later I notice that half the keys arent sticky anymore... like the backspace/enter keys etc. Obviously the other ones not so much because I barely used them! So best way is to grab a paper tower, apply baby oil and just clean your keyboard as you would if you used a cleaning agent.
works like a charm
