Hello, my name is Zeb (not my real name) and I collect the mid-1970s and older soda bottles mostly acls but I am starting my collection of embossed soda bottles, I've been collecting for one year starting May 31st, I live in southern Missouri and find many of my bottles in flea markets and yard...
I use a bottle cleaning brush, it's about 1 foot tall and expands when its in the bottle it works pretty good, however, it doesn't take away the oxidation.
Here's a link for it...
