how best to clean antique pepsi and coca cola bottles?

The one on the bottle and the one in the right frame is. The hanging one on the left is a fake from the 1970s. I also have a couple walking with those who see major signs. Ebay has made the value down to them, unless they are in excellent condition. They are in very good condition.
