@nottingham82 - Yes! Very sooty indeed. I place the leather in the kitchen sink and run cold water over it to get the first layer off, you're right, that stuff will smear and stain. After the first rinse I rub the burn gently with my fingertips still under running water. Then I rub gently with a soft washcloth to get the final layers of soot off. If I'm in a hurry I pop the leather in my dehydrator to dry and, if not, I just set it out for a few hours.
I like the resolution in your photos. I may have to switch to .1 instead for the next burn. Does that double the amount of time it takes?
