I have some old (4+ years) zymol leather cleaner and conditioner, shown here:



Amazon.com: Zymol Z-507 Leather Cleaner and Z-509 Leather Conditioner: Automotive



Should it still be OK to use? I have a 2009 BMW M3. I used some Mguires spray on leather cleaner and was not happy with the results (greasy, left spots). I am hoping this will sort that out.



Any advice is appreciated,

Dan
