Here’s a great “off label” use of an old product for a completely different application that a guitar player turned me on to years ago. The Zenith Tibet Almond Stick is an oil- and cleaner-impregnated plug that comes as a tightly rolled up cloth in a metal can. Its original use is to “efface 1,000 scratches from pianos—radios—furniture—etc. It’s amazing!” I use it to refresh old strings on guitars, banjo and mandolins. Just swipe the stick along the strings, then pinch each string with a rag and slide along its length. All the nasty bits of rust, dirt, and finger cheese come right off. It’s especially good at helping to remove the crud that get trapped in the coils of wound strings and restores that brilliant “new string” sound. I also like the art deco inspired litho steel tube it comes in.
By the way, it will last forever: my 40 year old stick is still going strong!
