clr always worked great for me to remove rust. Soak each bottle for a few minutes in the stuff and then scrub the rust away. Its calcium thats the biggest problem. If it wasn't for that I'd have a lot of spotless super shiney bottles. Swiz
nice stuff, the dump I've been digging, I've dug up about 10 of the listerines, they have tooled necks so I keeped them, then started to leave them, they are nice looking bottles, another bottle that is in abundence at this dump, is the cobalt magnezium, must have 10 of those and dug another 20 tops and sides, people must have been sick around here
