"Wet" cleaning doesn't necessarily imply cleaning only with water. Nrchy made it clear water was the 3rd step in a multistep process.
The non-water soluble contaminants on new vinyl are removable with water-based solutions containing other active ingredients. The final pure water rinse simply removes trace residues of those cleaning solutions, and perhaps "dirt" that was loosened by them but not quite removed.
IOW, I agree with Nrchy.
