I have a 2001 Lexus GS430 with black leather interior. The leather is pretty dissapointing. It has kind of a hard rough waxy feeling to it and not the soft supple feel I want. I have tried several products to try to soften it up like Mequires conditioner which did not help, I then tried Griots leather conditioner which did not seem to do much if anything, I then ordered Leatherique which from reading on the internet is supposed to be the best at treating and softening up leather. I am pretty dissapointed after spending all that money on it and reading all the praise that it seemed to have no affect on the seats either. I just tried Griots leather rejuvintor and it did not have an affect either. I have applied these products with a heater in the car to warm up the interior and let them sit in the sun during the summer. Is the leather in the Lexus GS that poor quality and supposed to feel hard and waxy? Does anybody recommend any other products to treat the leather. Someone suggested using Fast Orange to clean the seats as it will remove grime crud and grease that other products can't but I am unsure if it will harm the leather. I thought leatherique would work, I only did one application at a time but I think I will give it one last shot and try 3 applications and then covering it up with saran wrap. Anybody have any other suggestions?
