I've got a dresser whose drawers get stuck and won't open. Nothing is blocking them, they just seem to get stuck on the runners. None of the runners seem loose or damaged, so I don't really know what's going on.
I found some sites that said to try and rub some wax on them, but this didn't work. I just used some paraffin wax, is there a better solution?
Should I try to sand them down?
I've attached some pictures of drawers and the runners.
EDIT: None of the runners are loose, and the wax didn't work so I'll try sanding them this weekend and posting an update. Since none are loose, can I assume that they are still square?
