Heavy Duty leather cleaner & conditioner?

[rvx290]

I have a set of old leather seats to clean up which are slightly dried out, but mostly they are just extremely filthy dirty. Any recommendations? I am wondering if its safe to use Meguiars APC for the cleaning part? As for the conditioner, I am looking for something that wont be too glossy/greasy

Us the leather treated or none treated leather?

1z deep plastic cleaner seems to be a favorite and work better than opc

I love gliptone. It's great on both coated and uncoated.

If you want the best for uncoated use leatherique.

I actually did a test a couple days ago regarding the cleaning side of this subject:
