Yeah I’ve seen that video before. I have tried Super Clean and all I can say is that chrome on models must be way thinner than anything on vehicle plastic parts, because that’s something that I left a part in for 2 weeks with nothing to show for it except it was real clean. If muriatic acid isn’t having much effect I can imagine what Super Clean will do. I have also seen them using Easy Off Heavy Duty Oven Cleaner with the same results, instantaneously, and I have also tried that with zero results. I’m thinking the plastic on models can pretty much be removed with anything.
