This book is one of a kind. It gives formulas for household cleaning, cleaner laundry, deck cleaner and more. It gives proper name of chemicals to use to make hand creams, soap, etc. There is so much useful information in this book that I haven't been able to read all of it in all the years we have had it. There isn't another book like this in print that we know of. We have gone to it many times in almost 30 years to look things up and it never fails to give us what we need or at least put us on the right track. If you want to save money, want to know how things work, how they are made, this book is for you.
