I usually just scrape with the edge of a blade. I was hoping someone had a

I've used fibreglass pencils with success

just stroke along the exposed wires. Easier than glasspaper and less
damaging than a knife.

Thanks, Peter. I had the same problem and also the same fibreglass
scratch brush - just never put the two together. Stranded copper that
had been black with corrosion came clean enough for either soldering or
crimping.

For other applications, CPC also have brass bristle refills... but has
anyone seen the same in stainless steel recently? They seem to have
disappeared from the market.
