it's not abrasive it is attacking the surface of the vinyl and removing a layer.
I would only consider this as a last ditch effort to try and get some more life out of an interior. The results may be favorable but I am sure you'll be trading it off for a shortened lifespan of the vinyl.
I had some decent success with mold armor and magic erasers. I will probably try this in places this fall when the boat gets winterized.
