What would clean your car upholstery that would be non-toxic?
I use vinegar and water to clean mine. One part vinegar to 3 parts water. It is non-toxic and removes Odor's too. I learned this from my mom. This mixture is good for cleaning. Part of my chores is to wash the kitchen floor. Not only does it clean well, it is good for the environment and safe for my dogs.
