Actually, the deterioration rate of unique items can be reset, theoretically. Yes, no need to tell me that it can't be done because it's hard-coded. I don't want to say more until I've had a successful test. And to those who have problems with unique items deteriorating there's a very simple temporary solution which you can PM me as I don't want to say it in the open. 
So you admit to having discovered an exploit, which you have not told the dev team about, but you are spreading around in private?
Please report this immediately as a bug, so that the dev team can confirm or refute it, and if you have, indeed, found a way to "reset" the deterioration rate of unique items, we can fix that.
