I've noticed a blackish to dark gray residue on my male and female threads, most noticeably on my pommel threads and the corresponding female end. My saber does have a removable battery (V6 Speaker Mount) so these threads do get the most use. I used a toothbrush to clean up the threads and applied a bit of the Super Lube from the store before I noticed the gray stuff.
How often should I clean my threads? What should I use to clean my threads? Is there a way to avoid the gray build up?
