I have an old roll of solder, Sterling taramac, 1/8 inch wide, lead free. I can't find any info on this on the internet and wondering if it is still usable or appropriate for soldering some 3/4 inch copper pipe together. Does solder degrade with age?

Use it... I have electrical solder that's 30+ years old that is perfectly fine as as good as the day it was made.

I believe you are correct. Thank you

As stated above, yes, your old roll of solder is OK to be used

If not shiney, I would use a brass or steel wool, Even a scratchpad may work. To remove any surface tarnishing?/Oxidation?
