Because Adam's has specifically formulated their two cleaners to clean synthetic materials like vegan leather. Just going at it with anything without checking for phosphates or ammonia compounds could permanently mark the materials, not just the vegan leather. I like Adam's cuz there's no residue, clean wipes with no streaking and it gets dirt and oil out better than other products I've tried
Don't knock it til you try it.
A little goes a long way.
