The outside of my worm is starting to get blueish discolor on it.. I'm thinking the inside of it must have a bit on it also.. What would I run through it to clean some of that up or rid of it? I don't want any of that to be in contact of my alcohol leaving the condenser. Thanks.

plug up the bottom and fill with 50/50 water and vinegar, let soak overnight, rinse well.

I just cleaned my worm with the method that ShovelHead suggested. I let it soak overnight and then let it drain into a bucket.

The liquid was light blue in color. I plugged it back up and poured in another 50-50 solution. I let that sit overnight and then drained it. It was all clear.

Question: Is the blue the sulfides that the copper "gets rid of" from the distillate?

Question: Do we need to do this procedure to the copper every so often? If so, how often?

Thanks!

The blue stuff is Copper sulfate and it's a poison. On my copper pot still column and my BH condenser extension I wash thoroughly after a run with soap and water and will rinse in a dish tub of 50/50 vinegar and water. Then rinse with water and dry the parts with a heat gun.
I only had that problem once, that was before I started doing the above. If you store your copper parts where condensation can occur be sure to check them out before useing. It would be a real shame to poison loved ones, friends, or yourself.
