Although I included links to these handy guides in my CSI: Carpet Scene Investigation post, I thought they deserved a post of their very own. First, from Fabric Link comes an alphabetical who’s who of horrible stains. From acid toilet cleaners to wine, there’s something for everybody. Also worth a look-see is 3M’s stain removal guide, which they bill as alternatives to using one of their own products. How magnanimous of them.
