At least your not washing out your tumbling media like some I've talked to. gypsyman
Hey now, every once in a while I throw some long strips of paper towels in my tumbler to suck up some of that filth. It's cheap, and it kinda works.
Try used Dryer sheets, 2 halves are better than a full sheet,,works GREAT!

They/we use walnut because it's abrasive, I'm actually useing walnut media I got from work, they use it in a sandblaster to polish steel. If Almond had merit as a polishing media they'd already know and be useing the stuff. I think they do use it as mulch and plant bedding,
It's too soft for polishing.
