Many vintage keyboards I have seen have once been stored for long times with the cable wrapped around the keyboard's case where the plastic in the cable has "eaten" itself into the case over time leaving ugly marks.
How should I store the keyboards in my collection to prevent this from happening?
I usually store my keyboards in a box, with the cable wrapped into a bundle on the side, sometimes with a zip-tie .. but mostly in a big mess together with other cables. I'm starting to think that I should start changing the way I do, maybe wrap the keyboard and/or cable in plastic or in a plastic bag.
What do you do?
