Faucet handle removal
I must sound like a complete idiot, but I cannot seem to get the handle off of my Delta series 1400 shower faucet. It is one of those long, curved handles, not the round kind. I have removed the set screw and put considerable force on it, but the handle will not budge. Obviously, I can't get to the parts I want to replace unless I can get the handle off. Is it just corrosion? I have used WD-40 to no avail. Any suggestions?
