My first post--be gentle.
A friend of mine donated about 30' of 3/8" copper tubing he found in the shed of a house he bought. It looked as though it had never been used and was in good shape. I took it home, introduced it to steel wool, wound it around a paint can and--voila--wort chiller. However ... I did get a few spots of silver-bearing solder on it while I was piddling, but torched the solder and removed it with steel wool and rescrubbed the beejeezus out of it (you can still see silver marks where the solder was, though). Took the coil inside and boiled it for 40 minutes. When I took the coil out of the pot I noticed a white residue along the pot's water line and all around the copper coil as well.
Now, I don't know if this is an ionic salt resulting from the copper/tin/silver of the solder and tubing combining with minerals in the water or what; could be, I'm not positive. I will reboil a few more times to see if it will subsist or hopefully disappear but in the meantime I was wondering if anyone had any ideas? Does this happen to anyone else and their chiller on a regular basis?
