I am trying to unclog my drain. The knob on my lift and pull drain stop is very worn I think. I don't want to call a plumber. I've been using pliers to try to unscrew the drain but to no avail. I need to know how I can unscrew it without calling a plumber or buying anything. I tried to use paper towels but that didn't work.

It would have been nice to know exactly what fixture this drain is on. Sounds like a lavatory pop-up but tubs have drains too. Befoewe can help we have to know what we're dealing with. Back to you, Tolm
