If you send a coin to get graded to NGC or PCGS they will and can determine if it has been cleaned. And it will be noted on the label. No doubt about that. It's probably the lighting.
Simple being blast white doesn't mean something was cleaned, just as simple being dirty or toned doesn't mean something is 100 percent original
Coin conservation might be thought of as cleaning, but the intent is different. For example, a recovered coin from the deep might be encrusted with organic matter (e.g., coral) and must be removed to reveal what the object/coin is. A conservation usually requires a step process to remove the unwanted to reveal the object. It's not an attempt to make the old new again; it's a technique to restore an object to a desired state. With more common coins, conservation might be taken to stop verdigris, the green matter that plagues copper/bronze objects. The coin surface might be further compromised otherwise. So the hope is to stop the growth by removing it. This may enhance...or ruin a coins presentation (while conserving it). Normally, it's a problem coin at that point, but leaving it alone renders it a doomed coin anyway. So knowing what you have and what you want to do with it should be considered before taking a step that can't be undone. I suspect many botched attempts find their way to the 'Bay and are sold off; buyer beware.
That's an interesting way off looking at it. 100% correct and that is why we buy coins in hand or upon an adjudicated public eye. Even that adjudicated public eye can be frowned upon sometimes.
It only matters if looks like it has.
Sounds like a George Berkeley philosophical question on perception. If a coin has been cleaned but no one can tell, has it really been cleaned?
For all practical purposes no.
It's always the same with threads like this. Same questions, same confusion, same misunderstanding.
Yes, you are correct. Fully 80% or more of all older coins have been cleaned. And tens of millions of them have been cleanly graded by the TPGs - and correctly so.
But here's the thing, there is no problem with coins having been cleaned - none at all. But there is a big problem with coins having been harshly cleaned. Cleaned versus harshly cleaned - the difference in the terminology explains and answers all of your questions.
When people say "coins should never be cleaned" - what they really mean is - "coins should never be harshly cleaned".
If people would simply use the correct terminology there would be no questions, no confusion, no misunderstanding.
When in doubt, stop and let the professionals deal with it or wait until you have gained the proper experience (which could be weeks, months or even years).
Thanks for saying this so I didn't have to.
If the brush scratched it, it's damaged. Soaking in acetone would have been much better.
I'm unsure of your level of expertise, and I cannot say for sure, not knowing more about the coin on question....but I rather think an expert will put your coin under a light and call it improperly cleaned. JMHO.
No offense intended, but its a certainty, a given, that it did scratch it. That said, it is extremely common for untrained eyes not to be able to see that. You cannot wipe, rub, scrub, brush a coin with anything, and I do mean anything, and NOT leave scratches and or hairlines on the coin !
Also, soap is almost a bad idea because it leaves a harmful residue on the coins. In some cases soap can be safely used, but only by those who know how to safely remove the residue it leaves behind.
As long as dip removes pvc haze unattractive toning sb no problem.
