Leather Cleaning & Conditioning Protocol for all brands

[jackthompson]

I have the full aniline kit for my one H/M chair and ottoman. However, I just got a used Hancock and Moore settee. It's in good shape. No cracking. I've been trying to just wipe off with a microfiber towel and use the upholstery brush on my vacuum. However it has beautiful tufting and associated folds which have some dirt and dust in them. I can't suck the dirt out of the button holes. (See pictures). Any suggestions for a quick clean up? All it has on bottom is H/M tag, but not other information about the leather, date, etc.
