I live in a new mobile home and have many interior mirrors throughout my trailer. There is a film that appears causing the mirrors to look dull as opposed to gleaming. They are high quality mirrors and were were transported from a wooden home where this was NOT as issue. I was informed that is was possible that gases emitting from the vinyl siding could be a possibility. What are your thoughts on the validity of this statement. I was told that TIME was the only solution and that the film would dissipate over the years. I value your opinion on this matter. Thank you for giving me an opportunity to VENT. ( pun intended )
