Bleach....
I don't use the armor all products except on the tires of my trailer. They may have changed their formula from the past but my bad experience with their product causing the cracking, stopped me from using it years ago.
Yeah, it shines the seats up and makes them slippo, but the suns UV rays actually dries the compond out, leaving a greater risk of faster UV damage. So, I moved away from that stuff several years ago.
Like a couple have said, I think Scooper mentioned a petroleum product, what ever it is you use, use in in small quantities till you know the results. It is trial and error and we all have our own ways of what works best for us. So, you should have a lot of different replies to help you decide.:cheers:
