Clogged American Standard sink
I'm a DIY newbie, and am having trouble with a clogged American Standard sink. I've tried the vinegar/baking soda trick without much success.
The main issue is, I can't figure out how to remove the drain stopper/plug to get at the main piping (e.g. to get a wire down there to unhook/unclog any hair, etc).
I've attached a few pictures of the setup. I've tried twisting the top of the stopper, as our old sink one would just twist off. But this one is offering a lot of resistance and I don't want to break anything.
Thanks in advance,
