Query: CleanCaf does what it says

Ran this through our Capresso machine and, wow, the crud it took out was amazing. Have had the machine for several years, but never cleaned it from the inside, only the carafe and the filter area. This was an eye opener. It even cleaned the coffee stains off of the gold filter and cleaned the inside of the stainless carafe so it looks like new. I bought (2) boxes and we will sure use it down the road on a regular basis. Great product!
