Wasn't my intention to start a cat fight guys, but in regards to the original question, I'll begin on the safe side as suggested and use oil and steel wool; something with which I do have some experience,and report results afterwards.
That's okay. Stan likes to start this sort of crap if Frank doesn't jump him first. Stan has this "thing" for me. He told how he keeps "files" on me for "future reference". Pretty funny, in a pathetic sort of way.
Be gentle with the steel wool.
I'm still looking for the ultrasonic that doesn't use ultrasound.
