Hello
Im a new to the forum and hobby Althought I got a Idea for cleaning you finds.
First off I do brew my own beer tastes pretty good to. A big part of beer brewing is the love for washing dishes NOT.
#1 your basic Oxi clean & hot water== works wonders
#2 this stuff can be found at home depot ( barkeepers friend) very gentle comet like stuff.
# 3 this stuff will turn a piece of grungy copper into a brand new pipe. (Star-san) this stuff is a very very very form of a mild acid. this stuff can be found in your local home brew store if you have a LHBS
I hope this might help someone.
