Suppose $2 is my variable. I have tried going from

awk -F\, '{print $2 ":"}'

to 

awk -F\, '{print gsub(/[ \t]+$/, "", $2) ":"}'

But it goes from printing something to printing nothing at all.

    You’re printing the result of the gsub, but gsub does an in-place modify of $2 instead of returning a modified copy. Call gsub, then print:

    awk -F\, '{gsub(/[ \t]+$/, "", $2); print $2 ":"}'
