Re: [new_distillers] Copper packing turning black - Replace or clean?
- Sounds like you have an oxidation problem - you know, when copper and steel are pushed together and moisture is introduced. I would use one or the other - as it is hard to clean copper scrubbers. If your column is stainless - stick to copper. If it is a copper column, use stainless steel scrubbers.Regards,Bwyze

With every run, the copper scrubbers pregressively turn blacker...
I assume this is from the copper/Sulfide reaction saving the distillate
from the Hydrogen Sulfide smell/taste.
My question is: Can I clean the copper scrubbers or do I replace them?

- I tend to agree with you, but and would certainlly do the magnet
thing, but a wash with lots of sulphur in it will turn the scrubbers
a dark color also.
Soaking in a vinegar solution would dissolve the crud and then I put
the mesh through the dishwashwer for a cycle.
