[QUOTE="Daenegger, post: 2128925, member: 74299"]Thank you for the help guys and thank you forum moderator for explaining the wide variety of things that can fall under a generic tag of cleaned without further explanation to the person who paid to have the coin graded. As far as my success rate is concerned I went a step further and bought some improperly cleaned coins processed them and sent them back in. They all came back downgraded to just cleaned. I also haven't had any coins I cleaned come back other than cleaned or without details. Usually it's the case that it was cleaned poorly already once before I took the filth off of it. Just as a heads up: acetone is inferior to acetic acid for killing bacteria and stripping off residues. It's harsher and it's vapor point is way too low to actually be useful. Both leave the same antimicrobial and water repellent surface treatment.[/QUOTE]
