I’m not sure about leather renovation or deep cleaning per se but I apply griots 3 in 1 every few months or as need arises. It’s easy to apply, gets out stubborn suntan lotion, dust and stuff. I also keep a handy little vac in the door card and frequently run it along the seat stitching to keep up with it. I have the lusso seats and these are easy to clean cuz it’s a sanded smooth closed pore leather . The other leathers maybe more challenging
