Tried 'em all except the bottled Goo Gone. There is less goo but nothing worked very well despite lots of rubbing.
GOOD ONE !Hot Water
Blowtorch and a bastard file?
Without effecting the blade
'Probly doesn't smell as nice as WD40.OK OP, if WD40 and blowtorch + bastard file don't work, I GUESS I'll go along with the crowd and +3 to Goo Gone. It does work, my wife uses ours all the time and prefers it to WD40. You gotta understand tho, I'm like emotionally attached to my WD40, it's my SAK of solvents, I use it for everything.
