Craig has to be one of the smartest guys when it comes to concrete cleaning. This cook book is one of the only reasons my business has progressed the way it has. In life, confidence is extremely important.. same in business. Once you get the cook book it gives you the confidence to further your education in your niche. Not only has this helped me with confidence on bidding and booking more jobs with the understanding of what the issue is I’m trying to fix. But the the confidence my technicians have when on job sites. All of my technicians have either the app, or the hard copy cook book on their trucks to make sure no matter what job comes up. They are able to tackle it. If you’re contemplating getting this book, stop contemplating and thank me later. Thank you f9 team for the insane amount of help this book has brought to my company

I’ve used F9 products both residentially and commercially for a few years and have procrastinated buying the cookbook thinking I’ve got this...25 years of experience has taught me to remain teachable; a fellow soft-washing buddy taught me a few tricks he learned from the cookbook and I couldn’t be more confident in stain removal !! Thank you so much for offering this invaluable source of information to us for free! You care about us and we care about results👍 I will continue to use your products and share with all my convention & vendor showcase buddies the before/after pics of your exterior cleaning solutions I used and the jobs I used them on. Thanks again

I will admit it’s not the fanciest app I’ve ever used but you don’t get it for the features. You purchase this app because it gives you Step by Step instructions to clean whatever substrate you may be facing. I’ve used this on many a job site and if the book doesn’t have the answer or your stuck on something the owner amazingly will answer your questions! This is an awesome company where they actually care about their products and the people using it! When I first started my first chemical purchases were the entire F9 lineup and this App!Ten8 Pressure Washing

This cookbook(combined with the 4 F9 products) are able to clean every non-organic stain we have come across in our power washing business. So glad we were introduced to Craig and his products several years ago, it definitely sets us apart from many other contractors. Great products and great company!
