I have used Inner Clean QD for about a year and I like it. It doesn't particularly spread very far, which requires more product. It does dilute well though so that isn't that big of a deal. I use it to clean, and then follow it up with a protectant. Without a topcoat the surface looks dry and untreated. As a cleaner it does well, but needs a protectant after that. The smell is awesome!

Overall a solid product.
