I change the strings the Taylor way which is one at a time. I can clean the fret board with the strings on (takes alot of time) and that is what I do. However, when I did take all the strings off my Yamaha A1M and cleaned and oiled the fretboard I made sure when I put new strings on the setup was to my liking. It was so there was no need for me to do it (I do my own setups).
