I have wiped my PlexiPlexi a 100 times with shirts and cloths, I don't see any bad swirls at all , but yes after a lot of wear there are tiny micros... Such is life. I wouldn't have it any other way.
I don't get the people who comment and complain about it though, it's not like Panerai lied and deceived saying its an unscratchable Plexi and or advertised it as a sapphire lol
It's an implied risk, but certainly way overblown
