<HTML>Hi list,  I was at a church today for a cleaning,and tuning on a small grand.I used a yard stick to clean the soundboard,under the strings.It worked a lot better than a soundboard steel.It is flexible,but stiffer,so you can push a cloth easier,and a much thicker one.It is also very soft wood,so there's no chance of scratching the wood.You can also insert it at the treble string break and cover the whole board.Push the cloth to the top of the treble,and with the action out,you can remove the cloth with your hand.
