Also make sure there is absolutely no water or oil on/in the affected area , and get down to bright metal (a Dremel with a wire wheel should work nicely) please wear safetyglass's Tom , you probably know this, but the wire wheels throw out wire bits with astonishing speed...especially the Chinese knock offs. 🤕
Thanks for chiming in Bruce. Plan on removing the lines first, keep heat away from painted areas. Have tinned several steam lines before, know about oil and flux. Have picked several wires out of clothes and one in the cheek, of my face.
I always where glasses, even to blow my nose.
