See photos. On the one, the cross-bar broke off so I tried using a tub drain extractor with teeth, but that didn't work. On the other, I'm using an extractor that locks onto the cross bars. Neither one will budge. I tried putting some rust remover and CLR on the drains. Still no luck. Am I doing something wrong? I don't want to risk damaging the tub; how should I proceed? Thanks for your help.
