This book was a follow-up to the authors' "Speed Cleaning." "Speed Cleaning" was about how to do weekly cleaning chores; "Spring Cleaning" is about how to do the more heavy-duty stuff.
Like the first book, this one emphasizes using the right tools and working efficiently. It also has line drawings in the same style as those in the first book, though not as many of them, which is too bad because the drawings were one of the things I liked best about the first book.
This is a thicker book than the first one, and probably more useful as a reference book than as a guide to be followed from front to back.
Of the two books, I think the first one, "Speed Cleaning, " is the most useful and also the most interesting to read (which is important for people like me who tend to be "armchair" cleaning-book readers, who like to read these books without necessarily putting any of their ideas into practice).
