Leatherique Leather Rejuvenator/Prestine Clean Pair 8 Oz

Highly recommend. I used it on my M3 and it smells good, safe and not chemically odorous. The leather felt way better and I suspect will make it last longer. It didn’t take too long to dry and soak up. It doesn’t leave that gross shiny residue and so far has kept my seats nice. Worth the price and should last a long time cuz you don’t need too much of it.

Careful on step 2 it can sometime take the color off

This leather rejuvenator worked really well for me. It took some time, to take effect, but it really restored my water damaged car seats. My project: 2009 BMW with optional 'Dakota' leather that was in pristine condition before.... The windows and sunroof were left wide open in an all-night rain. Not just a little wet, SOAKING inch-of-water on the floorborads kind of catastrophe. The leather was totally waterlogged, swollen and mushy, then shrank when it dried so the seat bottoms were hard and cardboard-like. For a couple-weeks I tried daily applications of mainstream leather treatment, with no effect. Then got over the shockingly high price and bought Leatherique rejuvenator/pristine. The stuff is nasty and sticky. Hard to wash off your hands. I applied it only to the seat bottoms initially and left the car in the garage for a few days (June in Houston, so quite warm). After cleaning with the leatherique cleaner, I noticed that the surface texture was a little better, but the leather was still mostly shrunken. I read somewhere that leather like this is sealed on the surface, so I didn't expect instant results, but it looked like the oils were getting into the leather (there has to be some surface permeability or the water wouldn't have soaked it, right?). I did two more multi-day applications over the next couple weeks and saw incremental improvements each time, but it took several more weeks for the shrinking to gradually relax. I assume this was because of the oils slowly diffusing through the leather. During this time, I also treated the shift boot and parking brake boot. The parking brake boot looked fine, but was always stiff and felt paper-like (in the 2 years I have had the car anyway). Since the shift boot and parking brake aren't really ever touched, I just left the oil on them for the last few weeks, and both have shown a remarkable improvement. I don't think they are the same quality leather as the seats, but both are feeling much more supple now, without a feeling of papery-crispness.

used on my S55 2004 leather seats which made it much softer ... left it for 2 days on the seats. note: the leather gets even more softer in the next 2 weeks after the application

On a 2002 F-350 with neglected leather seats, I used almost a full bottle, taking 3 heavy applications. It took 3-4 days for the oil to soak in, but it does work and made the leather soft again. It does not make bad cracks go away, and may have actually caused a couple of very bad cracks to open up. What I learned was to take care of leather seats, more often than every 20+ years.
