Quoted from jboner1058:I wish I had a nicer apron. This one has a dark square on the right side from someone removing the venders decal prior to me getting it and some of the gold ink came with it
Are you sure it pulled paint and is not residue from the adhesive left over? If leftover adhesive, depending on its nature, I've used alcohol, naptha, Novus 2, or WD40 to get stickers/adhesive removed. Of those four the Novus 2 has abrasive in it. You might try on a part of the black to see if any adhesive comes up.
I've never touched a DE instruction card holder so not sure if any of the above materials will help. On Gottlieb EM holders, where the screened art is the most delicate of any manufacturer I have ever treated, only the Novus 2 removed art. It was unaffected by the alcohol, naptha or WD40.
Buyer beware, YMMV, and "The enemy of good is better".
