For those repairing stuff made before 2006 what is the method to best remove
the tinning from the leads from modern replacements before using ?
The distinguishing feature is that its much harder to abraid with a nail
file/sandpaper than tradional Pb/Sn "tinning". It is one of my personal
quirks to abraid all components ,ICs,trannies,R,Cs etc before soldering, as
rarely new stock replacements.

The Commission naturally expected you to destroy all your old stock.
