So a relevant question whilst on the subject of conservation, what is the actual difference when a TPG does this and someone at home perhaps going through a similar process? If a TPG picks up on this it gets a body bagged label stating "hairlines cleaned" why are TPGs allowed to do this and it's ok, yet John Doe gets a cleaned label.
The other gripe i have is to do with the Matt proofs wiped at the mint, i got a PF62 grade for hairlines and IMO it was better than a lot i've seen in that grade, but Catherines also has hairlines on the REV from cleaning and gets a 66 grade, so are we talking favouritism towards certain submitters?
