+1!
I use 0000 steel wool to rub down the actual fretwire, it gives it a great shine and feel. I also use it for cleaning the actual fretboard.
I rub the fretboard lengthways(opposit direction to the fretwire) and it cleans off the grime and sweat.
Once it is done, i wipe off any wire wool thats left on the fret board, I make sure the board is clean and then apply a healthy dose of lemon oil. usually it drinks it up in no time and then i just give the board a nice buff with a soft cloth!
All ready to play and feels smooth as hell!!
