This thing just plain works! Grime that's embedded in the patterned vinyl and/or leather seating, oil or hand lotion residue found caked on armrests and steering wheels, none of this stuff has a chance when you engage this little bruiser! Spray a little Power Clean, Fabric Clean and Protect, or even a shot of ONR-enriched steam, and then scrub in a "jitterbug" pattern to loosen grime's grip on those surfaces! It's been a great time-saver for me, as I've eliminated the need to use several brushes that usually leave stray bristles behind, while still not getting into the cranniest of crannies like this dude can. I'm very happy with the VLB, and you will be, too!
