Old Zymol Leather Cleaner & Leather Conditioner

[DBordello]

I have 4+ year old Zymol Leather cleaner and conditioner (Z-507 & Z-509). Do you think that it is still OK to use?



I previously used a spray Mguires leather product that I was not satisfied with. It was greasy and left spots if it was not adequately whipped, with overspray problems. I am hoping to clean that up. I would like to get the matte factory finish back.



I have a 2009 BMW M3 with black leather.



Any help is appreciated.

I doubt that anything could be good after 4 years, but at Target, I got some Zymol leather cleaner and conditioner and both were under 10 dollars.
