I'm not sure if we have the same interior, but I did a small detailing work inside the vehicle today.
My car is just 12 days old, but it sure did change the appearance
.
I used Ultima Interior Shampoo Gel + Ultima Interior Guard Plus.
The right side has been taken care of, the left side is the original look.
...hard to see the difference...lets remove the blue tape and use some flash...:
Well, quite some difference I must say...from gray-black to black-black.
It took me less than an hour to do the whole interior.
A photo of the passenger door afterwards:
Ultima Interior Guard Plus doesn't add any color to the surface...it is just protect the trim from UV-rays etc.
There are many other brands also, and I have tried a lot of them...but right now Ultima is one of my favorites.
