so i'd say solutions pog is a d-Limonene based solution and chemspecs is various petroleum distillates ... both will work im sure
I mostly use good ol' white spirit POG

i know it would have worked well on the sticky tape the OP mentions .
I found this online chemical sales site , selling most of the popular constituents of popular carpet cleaning products ... perhaps not wholesale prices , but you could save or make your own desired strength products ..
I know most people couldn't be bothered
