looks like the original small biro mark should have being treated with the solvent on a cotton bud or even something like a tooth pick and gently agitated and blotted .
But instead they just poured some solvent on and gave it a good rub .
The outer ring might disappear after just gentle hwe or handmit and foam . But id sat there is a little general distortion from the solvent that might never go fully but might not be noticeable standing up .
Perhaps the original little mark will come out more with solvent ... if that didnt work id be putting a little peroxide creme on a tooth pic and applying minutely along the line .
