David I've been a member of the NGC site and the PCGS site longer than I have been a member of this one. I still read them both, as much as I can. Used to post on both quite actively. But most of my time is now devoted to this site.
And I have known Conder since the days of the old Coin World forum which was before Coin Talk even existed. Same goes for those you call the big dogs. And I have read, numerous times, everything they have to say. And they in turn have read what I have to say.
And yes, I am well aware that there are those who use oils, Blue Ribbon, and many other concoctions on their copper coins. Not only to clean them, but to preserve them. It is a practice that is quite old, dates back to the 1800's. And some of the people who do this are very well known in numismatic circles. Many are even considered experts.
However, for every 1 you can find that follow these practices, there are 5 more who are just as well known and respected who will tell you to absolutely not follow them. You may count me among them for I learned in the 1960's the dangers of these practices from my grandfather who had been a collector since before 1920.
Now, all of that said, all it amounts to is a difference of opinion. Some people would rather contaminate their coins with oils and such, granted in order to protect them, than they would use modern storage methods. Which can do the very same thing by the way - without the oils.
