Re: Cleaning stained vinyl headliner
Yes TA will strip some of the vinyl surface, just as will many other aggressive cleaning product. After using TA, and wiping with a damp cloth you will see a slightly different surface texture/reflection. An auto store vinyl protectant will restore the surface finish appearance, but it may have more gloss than the original and will probably need to be repeated every year.
