See, this is a quality use of public university funding:
The University of Illinois' Stain Solution web site gathers exhaustive
remedies for hundreds of common, hard-to-remove stains in one
easy-to-search resource—with surprising specificity. Did that coffee
stain come with cream or no cream?
The site offers a variety of stain solutions, including for difficult
ones like blood and ink (including fountain, red, and India ink). It'll
tell you exactly what kind of tools you'll need to arm yourself with,
and the procedure for removing it. Best of all, the explanations
highlight how to remove the stain from different places, like from your
carpet or your clothes, along with alternate methods.
