Hi guys... I am here with a problem. I have this piano, it is a synthesizer, an expensive one, Roland A 90. So, I was fixing the house and I came into the studio where the piano is and I left an Air Wick scent bottle on top of the keys, that was a few days ago. A moment ago I noticed the smell from the room and I came and I see the Air Wick that I left (instead of pluging it to the wall) dropped and melted two keys!!!! Now lol, I am here with my girlfriend because I just got together with this guy and he is traveling and he told me I could stay at his very fancy apartment. He is a musician and I am taking care of the apartment and now I melted one of his pianos. So I am here with my friend and we took the piano that is heavy! And we put it (dropped it) on the floor so the oil could drain out. But there is no oil but two keys are sort of melted on the surface. So the question for you too... how can I make those keys smooth again? He is coming in two weeks. Is there a way to wax them? Thank youuu.
