Like EVERYONE else has said......use the Leather Conditioner in your car. Use it on your dash because it has a high SPF factor and will help prevent sun damage like fading and drying out. I use it on my steering wheel, seats, dash, doors...........anything that has vinyl or leather. And the smell is really nice too. Plus it does clean while you're putting it on. One thing to note: if you apply one coat and you notice streaking or white areas, it doesn't mean the product isn't working. What's happening is that the fabric is absorbing the product at different rates. You may need to add a second or even a third coat to get a uniform finish.
But it 's one of Adam's best products out there, bar none.
