LOL i sent Scottwax his first sample of Bi-o-kleen traffic lane cleaner, then his gallon.
Pro-chem is a large carpet, uphostery, leather, tile etc company.
For general soils, oils and grime i use prochem ultra-pac LVC for carpets and uphostery in cars, trucks and Suv's. I then filter down to prochems spotters as needed.
For vehicles with mostly food grime IE kids, dogs, Etc I move over to bi-o-kleen's traffic lane cleaner as my preconditioner. I still pre spot most everything with prochem spotters.
I use Red- relief, and Stain magic from Pro's choice for red and orange dyes depending on if they are natural or synthetic food grade dyes. For yellow staining I use pro's choice urine stain remover.
