I did not see any difference using the entire tube and, due to its consistency, a large amount of the product is needed to wash all sides.

I believe that overall it did a good job in cleaning the plate and stone. The ingredients are quite "organic" and the activated charcoal it contains may make a difference, although it is also trendy. It creates excessive foaming, which personally bothers me because it requires thorough rinsing. I don't know why, even though it doesn't contain SLS. I contacted a representative of the company via email and asked him about the foaming issue. He conveyed the information from the manufacturing plant that they do not use SLS or similar substances in any of the products they produce. So for me, it's okay and I occasionally use it. I consider this quality of responsiveness to a customer to be exemplary, it says something about the company.
