We use a 2% sodium hydroide then follow up with a 3% acid wash, good rinse then distill.

We do a light caustic 1-2% then rinse and follow with a heavier Acid wash (phosphoric) 3-5 %, Then a really good rinse before distilling.

Works well for us.

We use an Acid Metal Polish, from our chemical guys, for the outside. It's a powder you mix with water and it's AMAZING for polishing the outside. We follow that with Turtle wax to preserve the shine a little longer.

Just wondering what every one is using to clean and re-guvating their copper on the inside? coop

We back flush with our hot spent wine( acidic) then back flush with hot water then flush with hot water, then crawl in and clean with 000 steel wool.

works great

What is the composition of the acid metal polish? Thanks.
