OK, lesson #1 with a bullet: Do not under any circumstances SCRUB this leather with anything. I used a standard wash cloth and really got on a couple of small stains and ended up with suede. I'm hoping the conditioner will help here or at least not highlight the damage. We'll see.
Where I didn't lean into the scrubbing, the leather looks really good now, if not a bit dry. Some of the color has come back and is more even. Just wipe down with a damp cloth under an open palm. The leather will be dark with some light veins running through it. This is OK and will definitely come back to normal. Stop and let the leather dry when you see this.
I'll post an update when I get the KR conditioner applied.
