I woke up one morning to see my fogged up windscreen scrawled with numbers and letters on the side. I wiped them away, thinking somebody put a finger and wrote them. All was well when my windscreen cleared up in the afternoon, and it looked sparkly clear. But when night fell and the fog descended, the same stuff resurfaced again! I'd tried using water + cloth and scrubbing furiously, but it didn't work. I have tinted windows, so I don't know what solutions I can use. The Windex selection at my nearest Coles store are all not suitable for tinted windows. The windscreen is completely not scratched, and I can't feel anything over those words. Maybe a slight "embossed" effect perhaps. For the life of me, I don't know how to get rid of them. I've attached a picture of it, in case anyone has ANY idea at all. I'm a first-time car owner, so I'm really inexperienced with handling my car. Any suggestions will be really appreciated. Thanks!
