It's due to the depth of the vacuum adapter. Without the adapter to keep a vacuum on the valves the walnut shell goes EVERYWHERE. I scrape off the majority of the material up to the point of the manifold however without high pressure walnut shell it will look like its still dirty, but I can assure you it is just a HAIR thick. The priority is the valves. I ensure you we make sure the job is done properly for the customer, and encourage them to come back and take their own pictures as Marcus did on his. On the right side you can still see some marks from going in there with a pick, almost like a dentist would. Curiosity has me though, do they replace gaskets on a $250 valve clean, or are they reusing them? With the manifold off we make sure to replace them. They may not show up on the bill as we have to do a set price for the group buy but all manifold gaskets get replaced.
