non-fiction--4 stars. lots of handy little tips to cleaning every area of your home quickly. Some were brilliant, some were "duh!", and a couple were a little sketchy (for example, throwing away and replacing a vinyl shower curtain liner rather than cleaning it....vinyl outgassing is rather toxic and not something you really even want in your home at all, let alone replaced whenever mildew appears.) I want to get a copy of this to keep on hand though.
