During High school my Summer job was working in a Plating shop. I've seen how old chrome is removed, they use acid. Very, very strong acid, the plater would set a timer so he would know how long to leave it in. If you were to forget a part in the acid tank overnight, it would be ruined or not there at all. Also, I really don't like replating anything thin like a bicycle tubing. Remember the base metal has to be gound and polished, this was already done the first time around. A second round of acid, grinding and polishing would leave those tubes real, real thin. Not something I would do to a bike I would ride, a wall hanger maybe that's it.
