Need Help Erasing Ink

So I was working on a drawing and I forgot to make a small change before I went over the sketch with an ink pen and ended up inking the mistake by mistake. Is there anyway to erase black pen ink? I heard white ink might work. Admittedly my drawing knowledge and skills are amateurish at best and it probably isn't even worth fixing but I figured if I can still correct it, I'd give it a try. Any advice or help would be greatly appreciated.

There is white cover up ink you can use that works great. Very opaque, and flat, not like say using white out. Many use it to fix their line widths and of course fixing errors.

I'll look & see what I have after work later on
