I have an old tub and I've tried to remove the drain cover but it won't budge. I removed the screw and I have a pair of thin needle nose pliers that I could get into the grate but it won't turn. The thin plier nose inserted into the grate is so little that I think I may crack it if I use too much force. I've abandoned the project for now but I may resume it later on. Does anyone have any recommendations for how to get it off?
Here's a picture of it:
