I only ever strip clear wash,and spirit runs are obviously clear.
Every second run I see the the need to clean said Cu pieces with citric acid,as they are very mis-coloured,and it works. Two runs later and they are dirty.
How does anyone use backset/dunder as a copper cleaner?
Sir Robert, I'll assay a response to this cupric query. As per aidanmac (and I may have misread, but I think not) I'm only putting copper in my wash for the stripping runs and leaving it out of the spirit runs. So far, the copper comes out of the hot dunder gleaming bright. Not looking polished to militarily reflective glinting, though. More of an internal glow, almost chalky or slightly waxy; sunrise through fog - better yet, like the lipstick of a hippy girlfriend I had in the 70's. Gad, Kelly had a gorgeous mouth. Kissing her was like eating a marshmallow that ate back. So sweet and unctuously supple, her lips. And that copper-colored lipstick against her doeskin complexion... bestill my heart - and bestir my... other heart. heh
I haven't checked the ph, but I'll take aidanmac's word that the dunder is very acidic, which does the job on the copper. I've noticed too, however, that dunderized copper seems to air tarnish quite quickly. Perhaps the "softness" I notice is a weakening of its tegumental integrity caused by the acid. If I applied a bit of friction and force, perhaps it would yield to a true polished shine and not turn grey-and-black within minutes. I may have to try it and see.
william913: new to this could u please tell me if you use clearing agent is so which one?
New to it as well. I've used nothing more than sand through the hourglass and an algid lanai clear mine so far. Time and temperature do the job quite nicely.
Good luck in all you do and brew!-----------------------------------------------------------------------------
Update on my split pea exploits: Yesterday was spent stripping from noon to well after midnight. I had a 5 gallon Better Bottle full-to-the-brim with faintly floral wash that, at a little over 3 hours a run, dribbled out enough stiff liquor to water down for 2 30% spirit runs. Spirit run 1 went nicely today and I collected 19 little bottles (100ml in each) of nectar, which I dotingly diapered and set on a shelf to air for a day or 2 before I try my tongue and tastebuds with another cutting exercise. The other jug got a hit of baking soda and will have to wait a few days before getting put through the liquor-wringer; I currently only have enough little glasses and jars for one run at a time.
Meanwhile, split pea Sally, the daughter of my current distilling diversions, is still actively honeymooning beneath her thick quilt of krausen. She shakes and spits like she's going through an exorcism when I peek under the bucket lid. Which also reminds me of the girl with the copper-colored lipstick...
