This is actually a two part question. I am brand new to this forum. I have noticed a lot of people like using a woolite and water mixture for cleaning the carpet and fabric seats in their cars. But once you mix it and spray it I was wondering what you do? Do you scrub it in, blot it, let it dry naturally or waht? The second part of my question is about using this on your headliner. I have always been afraid to use anything on a headliner due to the fear of the moisture, etc making the headliner seperating and eventually hanging? My car is 15 years old so is this really safe to do?
