Green build up

Post by Shark »

I built new reflux still. Ran water then vinegar solution. Then I left it for a few weeks while fermenting. Checked still and I have green stuff all up inside copper. Pulled copper scrubbers out and they are totally covered in the green powder. Can I run water to clean this up or what to do before using for product?

Did you rinse out your still after the vinegar run?
Freedom had been hunted round the globe; reason was considered as rebellion; and the slavery of fear had made men afraid to think. But such is the irresistible nature of truth, that all it asks, and all it wants, is the liberty of appearing.

Try good wash with washing up liquid and soak in citric acid and good wash after.

And rinse immediately after in water .

In severe cases , the Copper Acetate will have to be aggressively removed . I Stainless steel pot scrubber on a stick will usually get rid of it .

I'd do a fast vinegar run, then rinse the column with water. Figure out how to back flush the still after use by connecting the outlet end of the PC to a garden hose and leaving the boiler drain open. :ewink:
