I have just packed all my cables away in bags sorted according to kind, and chucked them all in a box with a lid!
I wish I had done this immediately after the last time I cleaned them all, but I will do that next time I use them.
The plan is... take them out, use them, wipe them down, put them back away - so they stop accumulating dust!
I am feeling lighter and happier - this is good 👍
