Agreed acetone will get rid of residue from PVC although dont want to go down the acetone route again
Its more to do with the coin catherine or anybody else buys .
People pay a premium for a slabbed coin and can understand why....... only my opinion.
Although if a coin has been restored and the buyer is not made aware seems different.
All companies mention/reject cleaned coins although the servive to do it seems contradictory if not mentioned on attribution.
The premium catherine paid would he have been as keen ,but for this thread ?.
We mention cleaning on a coin but not if we did it does not seem right.
Nobody on here washes plates to restore them or preserve them.......cleaning is cleaning
