David: Your experience reflects mine as well. If there had been no change in the last several years, I probably would have quit using them. I use a 4:1 solution, multiple servings, and a drop of acetone on the strike point which I then go over with 400 sandpaper to take off the remnant curlies. Thanks for your input; I had never considered using them on Steinway--same results? Paul R-J
