How can I handle missing solder mask opening on PCB footprint?

I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?

You can use a burnishing pen, scratch brush, or fiberglass pen. It looks like an eraser pen but has fiberglass brush bristles come out. It’s much more precise, gentle, and safe than a knife, dremel, or sandpaper. Just pretend it’s an eraser. Normally used to scrape away oxidiation and rust.
