Well, thanks to the input offered by many of you and something I found in my shop, I have removed all the melted synthetic rag from my pipe.
I tried the oven cleaner that was suggested, but the goo was so adhered to the pipe that it didn't do anything. The carb cleaner I was using was taking forever and I was getting very frustrated.
So I spotted a tub of Mother's Mag wheel & Aluminum Polish sitting on the shelf in my shop and said "why not, I'll give it a try". Wow, was I impressed. It removed all of it in less than an hour. Now the pipe looks better than the dirty one on the left side.
So I want to thank all of you who gave me suggestions. And I also want to say hopefully none of you will do what I did----BUT---if you do---remember---Mother's Mag Wheel & Aluminum Polish!
