Clean the ear stud fasteners
The closures of my gold ear studs look like small open thumbscrews, you certainly know such closures. In these like to accumulate fluff, dandruff and the like, which one would not like to have there so much.
I have always tried to clean the closures with a toothpick or needle, but this did not produce a satisfactory result. Now I came up with the idea to use an interdental brush for cleaning. And lo and behold, the closure is jerk Zuck wonderfully clean. Do not confuse the brushes;)
