Have gained me the glass brush to occasionally clean oxidized solder and have to say this is wonderful. Since the brush, if necessary, even more to the point goes as expected, I now clean so that even small rust spots on the Roadster, which is surprisingly good. Above all, one can thus clean a small patch of highly targeted and in a small area, with sandpaper you can not avoid a minimum area. Degrees where you can not reach with sandpaper, such as rust in inaccessible angle glass brush shows its strength.
Something you have to be careful when you have to unscrew the fibers a bit further due to difficulties of reaching. Then it does not exactly push and scratch, but ideally something soulful and preferably 'stroke' in a direction, otherwise the fibers break off easily. This is turn fine, just takes a little longer.
The glass brush now part of the core equipment and is now an integral part of the case of the most commonly used tools.
