I like the pet safe deicer. It works really well so you actually just need a light sprinkling to create traction.
I wouldn’t use it to try to completely get rid of the ice as that would be cost prohibitive.
My dry lot - where they spend most of the winter - is 3/8 minus gravel. As much as I used dirty bedding, and thought it was effective, when I just had a dirt lot, I’m pretty unexcited about mixing dirty bedding into the footing that I just paid $$$$ to install.
