Well, under closer scrutiny under an Ott lamp last night, I could see faint remnants of those pencil marks so it wasn’t 100% but so much better that the proverbial rider on the galloping horse isnt going to see them when on a bed. I’m thrilled with how well this did. Marks that did not have Dawn on them are still visible but are on print fabric and kinda blend so I’m not as concerned about those as I was what was on stark white.
As to ballpoint ink, I’ve had decent results using rubbing alcohol on those.
