I have two screws holding on the metal disc covering the shower drain. Neither appears to be stripped. I would like to remove these screws to clean out the drain.
The problem is that the screwdriver won't go into the slots. I think there's some calcium buildup on the screw heads. I tried lightly scratching it with my screwdriver, but the stuff is really on there. I don't want to strip the screws by forcing too hard.
Is there a quick way to dissolve the calcium off the screw heads? Hoping that I don't need to go out and buy a jug of CLR for something so small.

Most of the time you can chisel it out with a scratch awl and a utility knife. You will dull the blade of the knife, but that's why they are replaceable. I also would use my $2 awl, not the heirloom one with the rosewood handle.
