Not Recommended. These wipes seem much too dry to me. I used one and saw no difference, but noticed the wipe is barely damp, and definitely not wet. So I tried a second wipe, and same thing. The wipes are still clean, as if they took nothing from the strings. As for the strings, the most fingered parts of the strings were still dingy, and the brighter parts still brighter. I could not see any difference after using these wipes.
