Lubricating the cork in a saxophone neck or a clarinet tenon. It turned out to be not a good idea at all, since the Vaseline speaks into the cork and dissolves the glue holding the cork to the instrument. But until then it does a great job.

Good job. But if you are like me they will be disordered in a week. It’s hard to keep entropy out of your life. Also, the oregano and cumin bottles are always empty.
