Review on 🧽 Ultimate Leather Master Nubuck Cleaning Kit: Restore and Protect Your Nubuck with Ease by Jeffery Pricinoc

I bought this to clean and refresh a 20 year old tan nubuck leather chair that had accumulated various dark brown stains over the years. I tried it on two dark stains in the same area, used the cleaner and cloth as directed, but the stains look the same as before. Worse, there's now a faint ring around where I've been working the longest. I'll eventually come back to this area and see if I can get this new stain out (I'm pretty sure it's because of the circular motions I used when brushing) so it's not as noticeable.
