I made the girls pick up all the “large” pieces ‘o stuff and then proceeded to CLEAN the carpet, windowsill, blinds and back of the couch. There was so much crud on it that I actually took the 409 bottle and sprayed it all over everything. It worked! 🙂 That and the floor cleaner did the trick. Of course, if you didn’t know, you probably never would have known of the mess behind the couch, but now, if you happen to look, you really won’t know. 🙂
