Hi guys, I’ve been driving a CLK convertible for 1 month which has a HELL grey interior. I’ve already got the leather perfectly clean with products from the company Lederzentrum.de ( 1000% recommended ) Now there’s only the even-fals HELL grey carpet, which looks quite taken away with the years (yellowing etc. ) Does someone know a !GUTEN! Carpet cleaner with which I could get something like that again?? Thanks already in advance for the hopefully many helpful Answers! 🙂 lg
