The Complete Handbook of Dish Detergent & Soap

I've managed a catering kitchen for twelve years and honestly thought I knew everything there was to know about dish soap. This handbook proved me wrong in the first chapter. The explanation of how water hardness actually interacts with different surfactant systems has already saved us from buying a more expensive detergent we didn't need. The chapter on troubleshooting film on glassware is worth the price alone. I've recommended it to three other kitchen managers already.

It's a solid reference with a lot of good technical information, but I was hoping for more practical, day-to-day guidance. The chemistry sections are thorough, but I could have done with a little less detail on molecular structures and more examples of what to do when you're in a rush and the glasses are still spotty. The troubleshooting chapter is useful, but it reads a bit like a lab manual. I'll keep it on the shelf, but it's not something I'd sit down and read cover to cover.

There's a lot of substance here and I respect that it doesn't talk down to the reader. I learned a good deal about why my rinse aid was leaving streaks and how to fix the concentration. That said, the business opportunities chapter felt a bit general and didn't give me the concrete margin numbers I was expecting. It mentions private labeling but doesn't go deep enough on regulatory hurdles. Still, a useful book for anyone running a commercial kitchen.

As someone who buys supplies for a small hotel chain, the selection chapter was very helpful. The cost-per-use formula is something I'll actually use in my quarterly budgeting. I'm giving it three stars because I found the writing style a bit dry and the first chapter went on longer than it needed to. I also wish the FAQ section was longer. The answers it gives are spot on, but there were a few things I'd have liked to see addressed that weren't.

Finally, a book that treats dish detergent like the serious technical subject it is. The breakdown of enzyme activity across different temperature ranges was exactly the kind of detail I needed to adjust our dish machine cycle and cut our chemical spend by about 15 percent. The installation section on calibration of feed pumps is something every maintenance person in a food service operation should read. This is a textbook-level reference that actually respects the reader's time.

I appreciated how grounded the book is - no fluff or filler, just real information. The chapter on understanding what dish detergent actually does helped me diagnose a recurring problem we were having with etching on our beer glasses. I would have liked to see a bit more on eco-friendly options and how they stack up in commercial settings, but I understand the focus is on practical results over trends. A strong reference that I'll keep in our office.
