My thoughts, too. That, and maybe some slight abrasion?

Watch it be something ridiculous like “the slight fibers are exfoliated from the paper by the soap, and those exponentially increase surface area of the degreaser in the soap and combine with the minute amount of bleach in the white paper towel to form a new chemical agent that’s highly effective in bleaching and degreasing that specific type of plastic and polarized fat, separating the two in a volumetric capillary action that essentially transfers the stain onto the fibers of the paper.”
