The only thing that seems to soften them up is use. Since I'm usually the only one who drives/rides in my car there is a big difference in the stiffness of the passenger and back seats compared to the drivers seat.
My seats are all pretty hard as well - even the driver's seat.
I have just spot treated wear points such as the driver's side seat bolster with Leatherique, but it was effective - it made the spots where the finish was rubbed through a lot less noticeable. But - it was a small area.
Did you use the rejuvinator oil or the pristine clean? Or both?
I'll start with saying, I've never heard of leatherique. I've used a lot of different leather care products. Most of them are commercial products for dealerships but that isn't one of them.
Leatherique can be used for leather maintenance but I think it's probably better known for restoration. The process consists of oiling and heating the leather to make the pores pull in the oil and expel contaminants. You clean, oil, heat cycle, clean, and repeat as necessary.
I've used lexol and have been happy with it. The cleaner is ph balanced, so it won't remove the dye coloring on the leather and also helps open up the pores. the conditioner will help soften. Its not a one time and you'll notice a difference kinda thing though. I do the cleaner and conditioner every 3 or 4 months and sometimes will do a conditioner treatment before a show.
I've used a product called saddle soap. It will soften the leather quicker. However i didn't like the sticky feeling you get right after using it. The tacky feeling does go away but not 100%.
Are your seats soft from the Lexol? I feel like Lexol is the go-to but I've never been wowed by it. Maybe I haven't used it long enough. I avoid saddle soap as I think it has a high ph and is bad for leather over the long term.
The coloring on leather seats is a dye. So if that dye has already faded, the condition won't help. The conditioner is best to prevent cracking and sun damage but you gotta maintain it from the start. On average they say every 6 months to clean and condition leather. More if the car sees a lot of use.
This is one of my main questions. I know Leatherique works on regular "bare" leather... leather that's been treated by water based colorants or dyes. I believe the edges of my seats are bare enough for the Leatherique to work, however, the center perforated part does not feel like leather. It feels like either vinyl or leather sprayed with some sort of thick protective colorant like the one I had to wet sand off my Jaguar interior. The problem with these protective colorants is that they do not allow the Leatherique to reach the pores of the leather. On these you either remove the colorant (I used fine sandpaper and a 50/50 mixture of isopropyl rubbing alcohol and ammonia) or wait for the leather to slowly harden, shrink, and crack. Has anyone got that center perforated section to soften up?
