I have used hair spray on ball point ink stains.

Happy for the OP and the removed pencil marks. Have had luck with similar treatment for those. As to the ball point pen...I was going to suggest hair spray as well. Not sure I've used it myself but it is the 'go to' treatment that I have heard for decades. Good luck.

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.

I didn't know you could still buy hairspray!

Thanks for sharing. I had a pencil mark issue just this week.

Thanks for the update, I am sure this will be extremely helpful to many.

Happy dance to you! So glad you got out the pencil marks!

I have a ball pen, Pilot friXion. It is for quilting, do your marking and run a hot iron over it and it is gone. Best thing I have found. It is only sold at quilt shops. It is wonderful. I have bought some for my quilting friends for Christmas.
