How should I care for the fine iron dust that comes off on the surface of the metal frame?

After bringing in new furniture, blackish dust can sometimes come off on your fingertips when you hold the smooth metal frame. This is a phenomenon encountered in products with polished metal frames, such as the LCH4 chair or CH8 chair from TXTR. In these products, fine scratches or iron dust may occur during the polishing process of machining the metal surface^[1][2]. Generally, polishing is a process that grinds the surface with an abrasive to produce a smooth shine, so fine metal dust generated while smoothing often remains on the exterior.

The care method is simple. The iron dust clinging to the frame comes off cleanly when wiped away with a dry towel^[3][4]. In general, if moisture touches metal dust, it can react with water to leave stains or cause rust, so it is safer to gently sweep it away with a dry cloth instead of a damp cloth.

hmmm, once wiped away, the smooth luster is fully revealed, so you may consider it as a first touch of grooming that brushes off the traces lingering at the tail end of the process.
