Do lead car battery terminals ever go bad and you can't clean them. I think I have one that can't be cleaned.?
The old-fashioned ones that you get from the auto parts store. Pure lead unpainted
Maybe the Chinese have made them so poorly they actually go bad this is the second one I can't seem to clean

Ted is correct ... but also you can get a little tool at an auto parts store. it has a part that fits over the terminal and inside is a bunch of bristles that scrape the lead making a new, better electrical connection. The other end fits into the cable connector and scrapes the inside of it for a better connection. There is even some spray stuff you can buy to spray on them to retard oxidation.
I've never heard of the terminals completely going bad. maybe a cell inside the battery has gone bad.

disconnect cables, pour coke or pepsi on them, then wipe dry and reconnect.
