I have 2 matching 64 Phillips bikes that have some very light surface rust but otherwise are in beautiful shape. I'm thinking of taking my daughters old kiddie pool and making a large Oxalic acid bath, has anyone ever dumped an entire bike in the bath? would the acid have any reaction with the zinc coated(I guess)spokes on the wheels? how about the hub? I've heard that it doesn't harm paint so I guess I'm cool there.All steel bikes right?
